My workplace does this for EVERYTHING. And they are always immediately obviously AI slop, both because we all know they wouldn't ever pay an actual artist to create graphics, but also because the people creating the graphics have no sense of style and let it generate the most generic shit possible with zero creativity.

It's definitely not helpful. It's just annoying and disgusting and a waste of resources IMO. But hey at least Powerpoint presentations have AI slop instead of stuff taken from Google Images!?
