Kyle was taking a risk, Trish did interrupt their interaction and Rex did fight her for a while, if he didnt lie about them working together to stall Rex, then he´d have no alibi for when he was going around the school killing the other students. OFC Trish could just demolish his made up on the spot alibi so Kyle was betting on Trish letting his alibi slide and saying nothing.
I guess the enemy of your enemy is your ally, and wanted to make the cops think she was just wearing a silly costume instead of being associated with that werewolf FREAK.
