Does anyone know how these keys could be used for TOTP? In case of Yubikey one could use an app which effectively acted as a proxy between the TOTP-based system and a hardware key. Does the Google key support the same functionality?

These devices don't have a real-time clock, so TOTP is out of the question. A Yubikey by itself is incapable of doing TOTP, too – it just acts as a hardware authenticator for the actual password generator. HOTP/counter mode doesn't have this requirement.

Yubikey does support storing TOTP secrets. It requires you use their app (desktop or android) which then provides the time component.
