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?

Thank you! And let’s hope it’s never made illegal, so we can continue to do things legally while respecting our internet preferences…
