45-9-101 deals with a "License to carry stun gun, concealed pistol or revolver". I read the snippet you posted as "this license doesn't give the state's approval for OC". 97-37-1 also contains language regarding deadly weapons "concealed in whole or in part". Open carry itself is not prohibited/regulated anywhere in the state code that I've found. I am not aware of any law or court precedent (other than the infamously vague statements by Chief Justice Lee) that define exactly what "concealed in whole or in part" means.
