All these companies do is make it easier to use wireguard, if you’re so afraid of them just use wireguard yourself, you’ll get the same effect

I remember figuring this out when I realized my vpn wasn’t connecting while I was inside of my secure folder, which acts like it’s own user profile

You need a VPN that can split tunnel by ip via CLI (although I think it’s also possible to set it up in an ovpn file, but I haven’t tried it). The only one I’ve found that can do this natively is proton, specifically the python community version.

I don’t know how this next part works if you use something that isn’t tailscale, but if you do then just set proton’s split tunneling for 100.64.0.0/10

Then, still on this machine, advertise the exit node from tailscale (you also have to allow it from your tailscale admin console). Connect to it from your phone, making sure to use the server as an exit node, and head over to ip.me to see if it’s working

If I’m understanding correctly, I think I’ve actually done something similar with tailscale. I run a VPN on my server and use it as a tailscale exit node (since it’s always running, I never have to worry about it turning off) and this allows me to connect to my server remotely while using a VPN, since Android also doesn’t allow simultaneously VPN connections
