i assume some have heard about the problems with the TPM 1.2 chip found in many Lenovo rigs
Microsoft has fixed the issue for bitlocker for windows 10 version 1803 so unless you are using an obsolete version of windows you might want to upgrade
while you are at it, make sure you have a backup of your recovery key in case of the unthinkable

I believe you are talking about the below security topic at Lenovo Product Security Advisory.
Please visit above site and find the appropriate actions.

any way to see which make/model of TPM a given machine has?
I have a T500 and an X220 at the moment, been thinking of a slightly more recent machine mostly for USB 3 so I can lleverage faster USB sticks etc
USB sticks are big enough for backups galore
According to tpm.msc I have a STM manufacturer which I suspect is ST microelectronics in my X220

The specified Lenovo Product Security Advisory described the affected ThinkPd models, it described your T500 and X220 are out of scope. As you figured out, tpm.msc can shows the equipped TPM vendor and FW version and your X220 seems to have STMicro. This security advisory is about Infineon TPM so that your systems are safe.

According to tpm.msc my T500 has an Intel TPM chip, so this means there are now 3 known vendors of the logic to be wary of.
Intel TPM seems to be safe
STmicro seems to be safe
The Infineon as described in the bulletin seems to be the only logic that is affected
to check with windows, press win+r and in the box enter tpm.msc which will bring up the windows management snap-in directly
