I'm glad you can eat all that stuff I can't eat any of the items listed. Let your meter be your guide. I manage alot easier with No grains.First, Gluten is not Carbohydrates. Gluten is protein. If you search for low carb flour you end up with a lot of gluten-free results which is quite confusing. Rice flour which has no gluten has 128g carbohydrates per cup!
I have found a high gluten flour from Bob's Red Mill that may work when mixed with other flours.
Carbohydrates in one cup of Vital Wheat Gluten is 16g.
Carbohydrates in one cup of Semolina is 124g.
Again, experimenting with different mixtures can result in a lot of work and a very expensive bowl of spaghetti. Not so bad though once I figure it out. This is why I was hoping someone had already gone down this road.
