We do not have uniformed officers

The only time that I've seen TABC officers in something that might be considered a uniform is when they work as bike officers in the Central Business District (West End and Deep Ellum) areas of Dallas. This is usually during the Friday night TX/OU Rally and they're wearing their TABC polo shirts, bike shorts and duty belts. Other than that they are dressed as you described, depending upon the weather.

My question is "Who ultimately gives the authority of letting these gentleman open carry during inspections?"

The Texas Code of Criminal Procedures and their agency's policies.
