By law they are supposed to check so actually they are liable.
If you look at the law, the vet is required to check and sign the passport at intervals and our vets are very particular. (I was made to go home and get mine when I forgot it). There's is a £5000 fine if you don't have a passport which is supposed to be reported by an attending vet should they find you don't have the correct one.
The vet is supposed to sign the euthanasia/death bit of the passport then the passport has to returned to the PIO within a month (I think).
Copied from horse passport regs 2009:
Procedure on death
13.—(1) When a horse is slaughtered or killed for disease control purposes, the official veterinary surgeon responsible for the slaughter or killing must, in accordance with Article 19(2)(a)(i) of Commission Regulation (EC) No. 504/2008, return the passport to the passport issuing organisation as soon as is reasonably practicable.
(2) When a horse is slaughtered for human consumption, in accordance with Article 19(2)(a)(ii) of that Regulation the occupier of the slaughterhouse must give the passport to the official veterinary surgeon at the slaughterhouse, who must record the identification number of the animal, mark the passport accordingly and send the marked passport to the passport issuing organisation as soon as is reasonably practicable.
(3) In any other case, notwithstanding Article 19(2)(b) of that Regulation, the keeper must return the passport to the passport issuing organisation within 30 days of the death of the horse, and failure to do so is an offence.
(4) The return of the passport under this regulation is the attestation required under Article 19(1)(c) of that Regulation.
Unfortunately lots of vets almost rely on the fact that owners have no idea about the law and so get away with rather a lot.
Most horses will fall under (3). Nothing here to say the vet needs to even see the passport and the onus is on the owner to return the passport to the PIO.
