what did i get chat banned for? i wasnt toxic..

We cant really help you when we know nothing about it. Chat logs will help determine the reasons for your restriction. So post those if youre genuinely confused. (Which i think you probably know, but probably just wanted some attention)

If you log out of the game then log back in, you should be presented with a reform card explaining why you were chat restricted.

Dont worry daddy. Riot banns you nowdays for just speaking...so much for a team based game huh
