Your info is a bit out of date. Epic already sold off Bandcamp back in 2023 during layoffs. Its owned by Songtradr now, who I personally know nothing about.

On top of using include mode, be sure to go into Qbittorrents settings and bind the network interface to the VPN. That will ensure that even if the VPN is disconnected or turned off for some reason, Qbit will not attempt to communicate on clear net. Some people would rely on Proton VPNs kill switch feature for that, but that is not available with split tunneling.
