You can raise the bar a bit. No one checks to see if a $5 bill is fake. There is no real upper limit on what the payout for a deepfake could be. TPM isnt going to save facial recognition ID like the IRS from being obsoleted by deepfakes. But, for things that go to trial a TPM dashcam with tamper evident packaging (that can be inspected during trial) is probably good enough for small claims court. You could add GPS spoof detection, put as much as you can on the tpm chip (like the accelerometer), and sign all sorts of available data along with the video, but that will up the unit price a lot, and for the kind of fraudulent payouts you'd be trying to stop, you wouldn't make it enough harder to keep it from being cost effective for the fakers.
