Seed phrase stolen but passphrase still with me

I understand that a passphrase is like an extra layer of protection, because without it you cannot access my hidden wallet.

However, what happens if a robber steals my seed phrase BUT NOT the passphrase. Although they wouldn’t be able to access my hidden wallet, they could, in theory, buy a Trezor one wallet and use the seed phrase to access my standard wallet, correct?

Assume my standard wallet had no funds in it, all is good. But with my seed phrase in someone else’s hands, I would want a new seed phrase. Could I create a new seed phrase and access my hidden wallet? What would you recommend I do in such a case?
