Wikipedia seems to indicate that the Girls Gone Wild folks survived the lawsuit that you're talking about and were eventually driven out of business due to other legal problems.
You are reading into the dates far to much, and they didn’t survive the underage girl criminal and civil cases.
Subsequent to those underage cases which began in 2003 additional civil lawsuits were also brought against the company for other issues, but those underage cases were still ongoing.
A different example would be the Hogan/Gawker case which started in 2013. The company faced other lawsuits after, but it was the hogan case that pushed them into bankruptcy because it didn’t end until 2016.
