Is there an expression to say "keep your hands to yourself"? I'm looking for something stronger than "pa bat mwen".

Pa bat mwen is Don't hit me

Keep your hands to yourself would generally translate in Creole as Pa manyen anyen (Don't touch anything) or Pa manyen'm (Don't touch me)

But if someone is actually hitting you, tell him/her:
Pa leve zago'w sou mwen!
or
Sispann leve zago'w sou mwen!
Then let someone know about this.
