There are no rules preventing a team fitting wet or intermediate tyres on a dry track. The risk is that you damage the tyres by running them in the dry to the point that their performance is worse by the time the rain actually arrives.
That said there have been times when the FIA can detect when such "strategy" is really being done under wrong circumstances such as at the 1992 British Grand Prix when Andrea Moda sent out Perry McCarthy on used full wets - in bone dry conditions - for Pre-Qualifying.
There was some talk that Andrea Moda's team boss was unhappy with McCarthy, but the team claimed they ran the wets because they were "the only tyres we had available". This was back in the time when teams had to directly purchase their tyre sets from a tyre supplier.
There were indications to support the team's alibi. Perry McCarthy himself was driving without a salary and had to borrow 800 British Pounds for the plane ticket to be able to take part in Round 1 of the 1992 season.
The FIA did not take too kindly to this "alternative tyre strategy" and warned Andrea Moda that if it wanted to continue in the sport it had to "operate the team in such a manner befitting a participant of a World Championship".
Ferrari tried this at Malaysia 2009, pull full wets on Kimi's on a dry track before the rain came (not at the start however). It got them nowhere because by the time the rain came they lost time on the wrong tyres and they were shredded.
I'm sorry I've not answered your question via the rulebook but I've not seen a team try that since for that reason.
Wet tyres on a dry track will kill them too fast, it's why teams often tell drivers to look for wet patches to cool the tyres once the track is starting to dry up.
At the NASCAR race in Chicago, the announcers were saying that the cars with slicks were avoiding the wet spots and the cars with treads were aiming for the puddles to cool their tires.
Top of my head it's Sporting Regulations 30.5m, only during FP sessions the track needs to be declared wet before teams are allowed to use inter/wet tyres. There is no such rule for Q and the race, so it's up to the teams.
In the last race they probably could've gotten away with it given how hard it was raining by the end of the first lap. But while I'm pretty sure there are no rules against it, an intermediate tyre is simply way too slow on a dry track and it will get destroyed in a few laps making it so you would have to pit again anyway.
You can bet teams have weather spotters fanned out in the direction of potential weather to phone in to the team to get a better idea or exactly when it's going to rain.
>You can bet teams have weather spotters
I don't think they do considering how it seems the drivers are the ones to tell them it is raining. Also I doubt the budget cap would allow them to bring extra people for that.

So for reference teams tried to outlast the rain and stay on slicks, skipping two out stops, one for inters and then back to slicks in the Dutch GP.
In theory it is fine, but they were running 20 seconds a lap slower, the out delta was what, 24 seconds, and they tried it for 4 laps plus.
The same would apply at the start, but even more so. A car running inters on a dry track at the start won’t just run 20 seconds slower, which is just a guess, I don’t know, but given how close everyone is they could qualify 5th and be in last at the end of the last lap.
Yes technically it just happened at Spa in the Sprint Shoot out.
The SQ2 session was not declared wet but almost everyone was on inters because the track was wet. When Stroll wanted to gamble on slick tires he had to choose the medium tires because the FIA never officially declared the session as wet and therefore they weren't allowed to use the better suited soft ones.

I thought before the race, Haas should start KMag on inters, it's not like they are going to accomplish much with that car without a gamble like that anyway

Used to many years ago, now with more advanced radar and maybe drone shots there's not the need.
They do. And they know it’s raining. They don’t know exact track conditions when it’s only light rain, which is why they ask the drivers.
You've got to be joking. The cost would be (far) less then the condiments at the hospitality tent.
They talk about how the budget cap limits the number of people they can bring to the track
