"In the video game industry, games as a service (GaaS) represents providing video games or game content on a continuing revenue model, similar to software as a service.
[...]
Games released under the GaaS model typically receive a long or indefinite stream of monetized new content over time to encourage players to continue paying to support the game. This often leads to games that work under a GaaS model to be called "living games", "live games", or "live service games" since they continually change with these updates."
GaaS monetization can't be achieved without a central online service. Even with Hitman 3 a lot of content is locked behind the online requirement.
You can bend the definition as much as you want but this is what most people mean by" live service games".
AFAIK, yes.
