I have found only one chest in the general's possession that could produce a Talos amulet in its leveled loot drop.
And it's a generic religious amulet drop that could produce any of the other eight amulets as well.
I haven't looked at Mede's, though I suspect I'd have to look at quest aliases as well to make sure with him.
It matters not, really... He's already a participant in yet another Enantiomorphic Event involving a dragonborn.
