Changed out a cast iron bathtub recently. Looked at it the other day, as it
was being prepped for tile. On the corner, fortunately where it will be
covered by bitchithene, and then cement and tile, there is a quarter size
chip (don't believe metal showing). I put a coat of porcelain repair epoxy
on it and no sooner had I did that then the workers put bitchithene on it.
I think a worker droped a hammer or staple gun on it from working on the
lath on the walls or maybe when it was brought in, it was banged against
something. In any case, is it a rust problem waiting to happen? When rust
does start in a chip on a cast iron sink, tub, etc. does it eat like cancer
through the whole thing or just the surface of the area it is on? Is it
worth pulling the bitchithene off, sealing it properly and then putting tile
on or should I leave it alone.

IMHO, don't worry about it.
Cast iron pipe lasts what, 100 years, and it is not enamelled.
This area is not visible and it has been sealed.
I wouldn't worry.
