So am I correct in understanding that this could be used to make a tool to unlock any encrypted disk that relies on the tpm whilst something like luks or indeed any solution that doesn't rely on the bios being secure would be fine.
Note I'm talking about a stolen laptop not an evil maid situation.
Not necessarily. Luks can be used with TPM. Although I've never seen it in practice.
Most Linux distros offer a standard Luks with passphrase setup with just a single checkmark, but enabling TPM takes more work.
Sounds like luks is borked as well if youre using only tpm state to unlock, which you shouldnt
All of the LUKS integrations literally just store a password and then type that into the thing upon boot
