It would be more accurate to say they try and block the vpn providers and Tor exit nodes. In practice, they do have ~95% of Tor exit nodes blacklisted but major vpn providers it's closer to 40%. Vpn providers go through a lot of effort to hide their exit traffic and it's pretty simple to use a provider that has a reasonably robust cli to just rotate nodes until you find one that works

Connect

Test known-good video using yt-dlp

If fail, use vpn cli to connect to a new node

Reeat until success

If your provider let's you connect to specific nodes you can even store the last-known-good and use it on first connect until it gets blacklisted, extending uptime considerably
