You could make inquiry about lawsuits illegal. I have heard of companies that explicitly ask if you have ever sued a former employer, which crosses a line for me, because it's sometimes necessary to sue to secure your rights. However, even without deliberately asking, a company could learn, and it's not hard to imagine why an employer would be very wary of hiring someone who has sued a former employer. Being sued is an extremely stressful thing and lots of people go to great, even possibly irrational, lengths to avoid it. Ask how you would feel working for a company that had sued former employees. There are no good answers.
