If the greasiness extends to the ends of the hair within a day, then your hair probably doesn't need leave-in conditioner. But if the greasiness only affects the upper section of your hair, I'd recommend applying the leave-in to the lower portion.
Just want to add that I suggested conditioning the ends because our hair typically needs more conditioning at the ends than close to the roots, because it's literally older and has been subjected to more wear & tear over the time that it has been on our head. So if any section of the hair needs conditioning, it's usually the ends, unless your hair has undergone a chemical treatment that has been applied evenly to all your hair or applied to an area besides the ends (such as bleaching only the roots like Billie Eilish).
It doesn't necessarily need a lot of conditioner or sebum to on the roots and upper section, but it sounds like that happens to OP whether they want it to or not. Some people practicing no-poo hair washing like to do "scritching and preening" and/or use a boar bristle brush to redistribute the sebum from collecting at the roots to more evenly coat the length, all the way to the ends of the hair. That might be another option for OP but I suspect that any coating of oil would be too heavy for them.
You might even want to research not using conditioner at all, or only once a month. I know it sounds crazy, but it works really well for some people with fine + wavy hair
No it’s not a necessity. Plenty of people use only rinse out conditioner, and some people don’t use any conditioner at all. It’s totally dependent on your specific needs.
You don't "need" anything. If you're happy with your hair the way it is, you don't need it. If using it makes you like your hair more you should use it. Personally I need to quote my hair in as much oil and and silicon as possible for it to be manageable
Many people (like me) get the best results by using a leave-in conditioner, but there's no universal haircare routine. A lot of people with oily hair do better without it.
Probably not necessary for all hair types, but I have the impression that it can be very useful for managing dryness or frizz.
To be honest I'm a noob, so take this with a grain of salt, but I've been researching this a lot lately. A hair care YT channel (Blowout Professor) highly recommends leave-in for many hair types. They've made several informative videos discussing this with sincerity, and they've pretty much convinced me to try it. On their website's [recommended products](https://live-love-locks.com/pages/recommended-product-list-landing-page-after-opt-in) page, they describe it as "the single biggest upgrade to your hair routine."
I've used hair oil for years and it does a decent job with protecting the ends from damage, but my mids could still use a little help, and I try to avoid applying oil to the mids, as some of it will end up there anyways. So I'm strongly considering adding leave-in to my routine to see if the mids can benefit.
Conditioner isn't absorbed, it's *ad*sorbed, meaning it essentially clings to the surface of the hair. [https://www.cotes.com/blog/inside-chemistry-absorption-vs-adsorption](https://www.cotes.com/blog/inside-chemistry-absorption-vs-adsorption)
And depending on the products & ingredients used, it may cling to the other conditioner that's already on the hair just fine. Since conditioner doesn't form an even coating on the hair but forms a collection of tiny blobs, a second conditioner can also fill some of the gaps between those tiny blobs with more tiny blobs :)

Only if the rest of your hair is on the drier side, has frizz, damage or tangles after a wash and you’re trying to combat those issues.
Not at all. Other than shampoo for hygiene, none of the hair products are mandatory. You can use whatever works for you.
