OK. Thanks everyone for the input. So came home and took the wheel off and pried the thing out. Not sure if you can tell in the picture but it was a piece of hard plastic. Dug around a little after removing and did not feel anything else in the wound. No leak.
Glad to have resolution and also thankful for the resource such as this board.
Also very happy that my fears about Michelin and Tesla were completely unfounded.
