My work is toxic and I only stay because I have paid time off (PTO)

I used to be the top guy but now my reputation is ruined. Management has it out for me despite smiling in my face like everything is okay. So tired and wanna leave today. Company policy is to pay out all PTO when I leave but there’s no law so they don’t have to. I’m scared they’ll screw me over if I just quit. I’m trying to take 2 weeks off paid while I do gig work and job search but I need to put it in 2 weeks in advance. Idk if I can deal with these people for 2 more weeks and wanna just tell my manager to terminate me TODAY.
