I'm proud of my deft non-confrontational solution to the student I suspected of using AI for a bunch of club stuff (since it's not an "assignment" my options to use school policy were limited & I didn't want to make the kid feel singled out/exposed)
"For all images on our material it's important to credit the artist or say if it's from a clip art library-- some students have worked hard to design logos, give them credit! All images should have a source!"

Magically all the AI slop has vanished.
