I'd suggest you find a vet behaviorist or behavior consultant with a bit more experience working with situations like what you've described. Your dog's lack of bite inhibition and the seeming ease with which he uses his teeth calls for working with someone well-versed in dog behavior and body language, and learning theory.
Check the links in the "veterinary behaviorist" and "behavior consultant" section of the sticky: Finding a Trainer, Behavior Consultant, or Behaviorist
The second trainer sounds good, but it also seems that she pushed too hard, too fast and didn't back off when your dog was reaching his limit. Did she explain why she continued knowing "was about to go down"? A good trainer will push a dog like that.
Also, what is a lead leash? Generally, the words lead and leash refer to the same thing.
Biting your son was likely a response to having been pushed past his limit by the trainer and his reacting without really thinking. But the fact that he did is concerning and warrants a more thorough evaluation by someone highly knowledgeable, IMO.
