I'm not a lawyer, but I've asked these kinds of questions to lawyers.
Paraphrasing, the answer I got was: "Anyone can sue anyone for any reason, and then we have a legal process to determine the result. If you're a director of the company, they're probaby going to sue you personally, and you're going to have to spend a lot of money to argue that you personally shouldn't be liable. Hopefully you'll be successful. It'll all depend on the facts, so you'll need to get sued first before I can give you a better answer. Either way, it's going to cost you money."
My conclusion is that the legal system is not super great when a bad-faith actor is involved. Though, really, it's also not super great when good-faith actors are involved, either.
