Get off your phone dude that shit does not help, if you posted this from a laptop then I have no response.

You could start by using the connection test on the mullvad website that checks for 3 different leaks.

VPN use is not illegal (yet).

Your ISP can still match your internet traffic to the act of torrenting - however they can not know what you are torrenting and the act of torrenting itself is not illegal.

Theoretically - using torrents to download free use material like you are going to do is 100% legal and above board. So what if you are choosing to use a VPN while doing it?
