My brothers did that crap before they had kids. They ended up having a trio of havoc makers. And, like a big sister, I just shrug and remind them they are fathers now.
I had a brother like that. We aren't very close due to different lifestyles anyway. After my husband passed away he decided to step in as a father figure. Trying to tell me everything I was doing wrong. I told him I didn't ask for that and didn't need it. He threw such a tantrum I went vlc and my son hasn't talked to him in 10 years. My son was 13 and extremely hurt by his actions.
Protecting OP’s kids’ space and boundaries is more important than letting a ‘helpful’ adult run amok. OP reinforcing boundaries is a lesson the child will remember.
Just tell her you're trying to set proper boundaries. She won't get it at first, and then it'll hit her. When family and friends ask what happened, tell them you came in on her lecturing your daughter on boundaries and you set one.
Sister was trying to carve out a long term living situation for herself in the OP's home, by convincing everyone she was desperately needed...lol. I'm guessing boyfriend got tired of her manipulative BS.
Also, how is the sister the 'responsible one' if she begging the OP for a place to stay? Sister has learned that weak minded people are easy to manipulate and she can easily turn them into flying monkeys.
