I've been looking through the previous video and while it's clear that AI is used (like in the transition of the shed). The rest seems to be too consistent to be entirely AI generated, details of objects remain consistent across shots. The short time-lapse also seems hard to fake. The new video doesn't seem to be using AI as much, but I did spot this illustration that seems generated. The video also references the projectsinflight channel which leads me to believe it's not based on an LLM generated script and the author does understand what he is talking about.

If it was a fake I can see why someone would do that. The Patreon brings in €285.6/month, coming from 140 people. His voice is also very monotone so I can see why you feel it's suspicious.
