IIUC, popular security key devices like the YubiKey securely store a private key, but only allow it to be used for specific authentication applications (e.g. OTP or U2F). Would the Tillitis Key be able to securely store a private key, then with appropriate authentication from the host, use that key for encryption and decryption?

Yes. I don't think that would be very hard to do.

Devices like the YubiKey can also be used for encryption (e. g. with LUKS or OpenPGP), digital signatures and SSH authentication.
