You need lawyers involved, but one of the most important things here is going to be what the LLC agreement actually says (is there a written LLC agreement, or when you formed the company did you default to statutory LLC provisions)? As an aside, you and some other posters are talking about this as though this is a corporation (shares, shareholders, etc.) but the specific type of entity (corporation, limited liability company, limited partnership, etc.) and how it is governed matters in a scenario like this. I agree with the other poster who said this may fall into the category of “too expensive to fix.” If you’re dealing with a bad faith actor who has the means to keep throwing legal spaghetti against the wall to see if something sticks, unfortunately they can make the cost-benefit analysis to turn against you pretty easily given the sums you’ve said are involved and the other priorities in your life. Good luck. I hate to see bad behavior rewarded.
