If you use Tor, you don't need a VPN. If you want to make your own VPN via tor, because you understand what it really is for, you are setting it up yourself in your own server, there are plenty of free open source software to do it (such as Wireguard).

Tor is not a browser, but sadly that's what they are making it look like lately, when they forked Firefox and bundled Tor with it, this was formerly called the Tor Browser which isn't the same as Tor itself.
