We could bomb / kill people before. We could propel arrows / spears / sling rocks at people before. All of which is an extension of walking over and punching someone.
Though sending a nuke from orbit on the other side of the planet by pressing a couple buttons does seem like the extension is so vast that it may qualify as "new".
I suppose any technology that can be used can be misused.
I misread you at first so here's an answer to if someone uses AI art:
Within the jokingly limited sphere of the discussion... "yes"? Particularly their artistic ability in that situation is being put to death slowly as whatever little they might have attempted without access to the tool will now not be attempted at all.
I don't know as much about if someone were to commission art from an actual person.
