I would go to the Verizon store with him. Hand the phone to an employee and simply ask if they can tell you if the phone has ever been jailbroken. If asked, just say you bought it off eBay and was curious (or some stupid story, they won't care). I guarantee they will say they can't tell.
I've sent phones for exchange through AppleCare, unrelated to JB'd, and never had a problem. All I did was restore as new before sending it in.
I call BS on the guy. He's just trying to bail on a deal.
