I think that perhaps systemd-creds gets it wrong? There really
does not seem to be any TPM support on this computer, either
version 1.2 or 2. In the bios settings, there is no "security
chip" entry under the "Security" tab and no other settings
pertaining to TPM in the bios at all. I ran Windows 11 in a VM
to check what it thinks about it and it also says that there is
no TPM support, either 1.2 or 2.

It is about 11-12 years old. It is a Lenovo M93p computer.
