It's almost certainly ai. Ai image models usually contain nudity but that's as taboo as it gets, they never have stuff like feces, vomit or gore in there. It looks like the ai substituted a grain or powder when asked to make vomit.
Plus the bizarre squiggle sign above the wall of items or the items that seem to blend together.
Security cam footage is a good fit for AI because it blurs the details, but it can't fix the simple fact that it cannot make a sensible output and cannot fix it without understanding context, which is the domain of general intelligence.
Prompts like that get you things like a person pooping out wooden logs. Close but not poop. I tried to get a ai image of a gas station bathroom someone destroyed with feces everywhere. I got a bathroom filled with wooden logs.
