As stated, it wouldn’t be a Tesla warranty. We had a CarMax warranty on a Honda Accord that had its transmission die. Took it to the Honda dealer, and CarMax paid them directly after the deductible. In theory, Tesla shouldn’t care at all - they are still getting paid for the work. The question will be if Tesla can figure out how to handle the billing to 3rd party warranty companies or if the owner will have to make the claim themselves.
