Is there a difference between an insulated breastmilk bag and a good insulated lunch box??

No

I just ordered a Freemie wearable pump (50% off right now!!!) and the collection cups are a little large and oddly sized.

For pumping on the go I’ll want to store the parts as well as a Dr. Brown’s bottle I’ve poured milk into.

I have a few great lunch bags already with a place to insert a frozen pack, those look like the same thing to me as breastmilk bags like Skip Hop.
