For LLMs, sure, but there's no way they're running LLMs on-device. Just classic AI models at the most

Image element recognition doesn't magically make actions happen, such as following a QR code link. The on-board AI would be more along the lines of pattern recognition such as reading text, license plates, people counts, etc. You could poison it by putting up the license plates but unless someone is actively looking for those plates it'll just be a small bit of metadata attached to the time code. The fact that they're stationary means it'll probably be ignored as well

Highly unlikely that any amount of significant processing is happening on-device. Wouldn't be cost effective

Shit! Why didn't I think of that?

They fundamentally cannot fix hallucinations in LLMs
