Is it the intent of this section that penetrations through the
1/2" drywall thermal barrier layer applied to the bottom of the
trusses be fire caulked or otherwise "fire proofed". (Conduits,
threaded rods, etc.)

No, based on the wording of the question and the use of the word threaded rod and conduit, indicating metal materials. IF the penetration is plastic and the construction type is combustible, then yes.
