My sister treats me like her punching bag and I don’t know if I can deal with it anymore.

Borderlines typically are unable to do chores expected of them by other people. They actually don't think it's fair. Talking to them is pointless. You will simply start arguments and never really win them. It can devolve into name calling and then she will hold what you said over you forever even if it was just something you said in the heat of the moment that anyone else would get over.

I've started to treat mine like a child. I do not ask her to do anything. I feed our pets and do all the dishes and laundry and do not even try to get her to do extra stuff.

You will NEVER be able to convince her to do anything that she doesn't want to do herself. Period.

I'm sorry you are going through this.
