Well you don't need to change your domain, just have a backup .ch in the same name. If you website is hosted offshore in a country with no Cloud Act treaty with the US then at worst they will only take the .com away and you just redirect your hosting to your backup .ch.
If you have TOR Browser you don't really need a VPN unless you are doing work related things outside your browser on applications that access the net.
I have a VPN but I use it to download pirated stuff...
