It really depends on the company. At every company I've worked at, either the company was too small to be able to invite that many people (it would basically be an all-hands) or the management was the ones planning these meetings. In my experience, the way to handle this is usually a quick Slack conversation with the meeting organizer starting with "hey, I saw you invited all of team X to the meeting - do they all need to be there or just Y". The response is almost always "I don't know anyone on that team so I just invited them all", and by initiating the conversation you are offering to help.
