I had a similar thing happen where my last name was also part of a trademark for a huge institution. As soon as I registered a domain with the name in it, I got an email from their legal department demanding I forfeit the domain to them or they would take legal action.
I replied that the domain was my surname, and that it wasn’t being used commercially at all, much less in the industry they’re in, and I actually got an email back saying they’d back off as long as I didn’t try to pull any funny business.
I wouldn’t touch this with a 10 foot pole. Squatting on domains that contain a trademark with the purpose of forcing a company to pay you out for it is illegal. There would need to be intent, but just going to court over something like that would NOT be worth it.
