In addition to offering "cash for keys" assure them that they can use you as a referral on their next tenant application, or offer them a short term-2 month lease.

Just keep in mind that there are further steps you'll want to keep to minimize the possibility that your entity is ignored for this kind of personal liability (say, if you were the person who didn't properly clear snow, or if your finances and the LLC's are comingled).And I agree with @Chris Seveney, insurance may provide adequate protection based on what's available to you.
