There is old project https://github.com/brianddk/trezor-tails but it's for Trezor web wallet. Now Trezor have GUI tool Trezor Suite with built-in Tor client.
Monero GUI now can work with remote nodes and also support Trezor T integration.
For make all above working it's necessary to make work Trezor Bridge daemon in Tails.
If you are interested I can test with both devices if you don't have it. I think it's will be interesting enhancement
