No. The source of truth is the manufacturer, so you don't need a "trustless" solution. You trust the manufacturer.

I wouldn't trust that they are who they say they are unless they can prove it. Also I don't trust anyone between them and me, including Amazon.

If they signed products with a cryptographic key, might actually be worth something as proof of who they are.

Sure, but that's just regular old cryptographic signatures + a web of trust. A blockchain doesn't help at all to prove who someone is.
