I've always been interested in trying to make some type of dahl or other Indian cuisine but I'm severely allergic to Cumin. This typically strikes me out for recipes with curry or chili powder. Does anyone have some PRO tips on types of curry (green, yellow, etc) or Indian foods that would allow me to venture off into this culinary space?   P.S. I'm also gluten intolerant and allergic to nuts and shellfish.   
Try Caraway as a substitute for Cumin. It has a similar flavour profile, just a little more intense. Some people prefer the flavour of Caraway and use it in all their recipes instead of Cumin.  I cannot tell you if you will be allergic to this herb, just like I don't know if you'll be allergic  to any other herb because you'r allergic to cumin. Caraway comes from an entirely different plant. It belongs to the same family as anise, fennel, dill, cumin, licorice, and coriander. So if you're allergic to all of those (i.e. the entire family), you're probably allergic to Caraway too. But if your allergy is restricted to cumin, you could give caraway a try.
