Oomis,
I assume the first line in your post was a typo – “milchig” shoud read “pareve”.
I think the issue is not the frum companies per se, but store brands in general (the frum companies don’t usually have their own facilities; they kasher the facilities which produce generic products).
It might be worth a shot to contact Manischewitz and ask them if Mishpacha brand chocolate chips have any traces of nuts. Manischewitz is a fairly large company.
