You’re rolling the dice there on corporate attitude. If they’ve got lawyers on their payroll already it will just be standard cost of business to sue yet another employee. Or just straight up vindictiveness.
You can't get blood from a stone, and there's no law that says you can't deliberately set up your finances to be maximally stone-like. IMO you should be doing this anyways so that the medical billing system can't decide to steal your life savings.
