It's rediculous though.. This guy is a sociopath

Lol, eight maids a milking... Slaves. He's sending you slaves darling.

Wait, just so I get this right... The board fired him; Then members of the board wanted him back; Now he's back and replaced the board too? - so did he pull an uno reverse on the board of directors or what? How the fuck does that shit work?

Looks gorgeous

Sounds frustrating, sorry to hear that

Jeez where do you live?

The 'robot' isn't the problem. This design is intentional and human made. Here in the Netherlands self checkout is the norm, even in very small grocery stores. However, it's super easy and not frustrating at all, because the stores TRUST their customers. The self checkout is super simple, you scan a product and put it on your bag, or backpack or whatever you have. No need to weigh the scanned products or anything. Nothing overcomplicated.

Now there are some control measures, but they are designed in a way to not be too intrusive or create unnecessary frustration: First, most places have a gate at the exit that only lets you leave by scamming your receipt (or if you go paperless, you scan your membership card on your phone). Also, some places do random inspection. But that's frustration free too - a worker comes up to you with a hand scanner, scans like four or five random items of yours and leaves. Boom, done.

Block the user... It's the easiest way to get rid of it

Empathy, Solidarity. Openmindedness.

Also, teaching them to be independent and self assured, being able to speak their mind.

Same here. Wireguard.

Just did a quick Google... There are some resources and tutorials online of people doing exactly that. Take a look!

Only thing you might need to change is the configuration for which port the pi-hole web server (UI) will be running on. Because octoprint already uses Port 80 by default, you might have to assign another port for the pi-hole service. (I believe it also defaults to 80. That would crash because it can't bind to the same port). That should be a pretty simple config change though.
