What to do with cruel dog breeders?

I have adopted a dog from a breeder here in Florida. We signed a contract that goes against some of the Florida laws not knowing until now. We have a 9 week Aussie Doodle who has gotten severely ill and has only hours left and it is too late to save him. Looking deeper into this breeder she has horrible reviews on BBB. She is cruel in a sense that she does not properly take care of puppies and over breeds the dogs. Many of the puppies become ill and breeder takes no responsibility, she uses different names and phone numbers to trick people, only meets at her “vet” for pickups. No one seems to know much about her but I’ve uncovered some but don’t know what to do. We can sue, yes I’m sure but is there a way to take her off the streets. People like this are only scam artists, she killing these dogs. The dog was only given vaccinations the day of the pickup and in Florida it’s supposed to be roughly 20 days before pickup. Am I wrong? She is killing these dogs before they even have a chance
