I've done some searching and can't find the requirement for kiln dried wood. Do you have any idea where to start looking again.
Check with your permit office about rough cut. It is in the IBC, but the code enforcement has final say.
I think you're right, and I believe it speaks of using graded lumber. Now-a-days nominal framing lumber from mills is ran thru a kiln. So the code may not require KD lumber, but it probably requires graded lumber
