Access without permission

Besides the known guzzoni server used for Siri and Apple Intelligence, you haven't described what exactly you are seeing or how your devices have been damaged. Since you now know guzzoni is not a person and not accessing your device without your permission, what are you seeing.

Feel free to provide screenshots of what you are seeing as long as they don't reveal any personal information.

Disable Siri, and disable dictation.

For one thing you are using a beta version of iOS which makes support unavailable. The first step is to remove the beta so see if the problem goes away.

How to uninstall iOS or iPadOS beta software - Apple Support

Beta software is not intended to be used on a primary device needed for daily tasks and should only be installed on a secondary device.

If you are using a firewall, that can block legitimate communications with Apple Servers for Siri use.

NB: This guzzoni.apple.com server has been in general use for a while, and isn’t specifically tied to anything recent.
