Yes, that is a problem.  AUCTeX's pairing should be made aware of
electric-pair-mode (including being enabled/disabled by
calling/setting electric-pair-mode as well).

A simpler way to disable it is to set electric-pair-mode to nil
(buffer-locally).  No need to check boundp of anything.

What happens is that AUCTeX's pairing commands call self-insert-command.
