AITA for demanding my sister and her boyfriend pay me back for drinking my whisky.

Agree NTA. Sister needs to drink a giant glass of (to quote the great Leslie Jones) “Grow the F**k Up”. There are consequences. I would tell her she has a month to move if it were me. If you won’t do that, you need to hold her accountable (her boyfriend sounds like a dick, but it was her job to follow the rules, not him, so she needs to clean up the mess after she so spectacularly $hit the bed). She needs to agree to a repayment plan for the value of the alcohol her guests consumed, and she may even need to agree to having some sort of restrictions on any unsupervised visitors until she can demonstrate she’s old enough for the responsibility of respecting others’ spaces.
