I want to know if she can get me evicted if she lies to the (illegally-renting) landlord and also if she can claim I have to be given eviction notice for saying she acts like a "b*tch".
The word "can" denotes the ability to do something not whether it's done rightly or wrongly. Theoretically she CAN get you evicted IF she lies and she CAN claim whatever she wants to claim.

Right now you are only speculating that it's illegal. You don't know. Call the code department in the morning and report it. Then get out as fast as you can because this is an untenable situation and the long term resident has the upper hand. Worse, if things start getting violent you could end up with a restraining order that will put you out on the street with a minute's notice or get you arrested.

There is no biding of time here.
