Ubuntu 22.04. Disable pihole feature not working. How to fix?

Here's the Debug link https://tricorder.pi-hole.net/jBH55Ynu/

I think I should have explained at the beginning that I did not set up my Pihole. I hired an online Linux person to do it. He took over my screen and spent about a half hour entering in lots of terminal commands. I had no clue whatsoever what he was doing but at the end my Pihole was working and blocking domains. I have no clue how he set it up or how he configured it.
