Yes, they are all live service games. As long as the product is out in public and actively being supported by developers, to us it is a live service game. This is one of those disconnects between what the public thinks the term means and what the developers think the term means (much like ["alpha" and "beta"]). Your own example of Smash Ultimate is very much a live service game - the online matchmaking, for example, is literally an online live service element. If a game gets updates and post-launch support, it's a live service. Also, remember that Wilson wasn't speaking to players or the press when he talked about "shared world features and deeper engagement" with regards to Veilguard, he was talking to investors at an investor call.
You've been using "live service" incorrectly. Most games today are live service games. Whenever a studio or publisher announces that there won't be any more updates for a particular game, that's them announcing the end of the live service part of the game. Live service games are not a bad thing.
