You can't sue them, and you can't remove your information. All these sites do is collect PUBLIC INFORMATION and consolidate it into one spot.

This public information is gleaned from public sources, such as registers of deed, lawsuits, etc. So there is no basis for demanding its removal. You can fix the problem by never visiting any of these sites. Then, you will not know. If threats are made against you, that can be reported to the police (if of injury, for example), or you can contact an attorney. But, as to public information, you are out of luck.
We do not have a client/attorney relationship until you make an appointment, we discuss your case face to face, I accept a retainer, and we explictly agree to enter into representation.
I think these cites just collate information from public sources such as property records, voter registrations, etc. Therefore, I don't think you can force them to remove you from their database.
