Just looking at it, I don't think I've ever been more on-the-fence about whether an image is AI or not. It has AI vibes, but no especially obvious AI artefacts. Nate Edwards is definitely a real photographer, too.

The guy's shirt has buttons on both sides

It could be snaps[1]. Google for "denim jacket with snaps" to see examples that match the fasteners in the image. I too can't decide if it's a real photo or AI generated.
