Interesting. I suppose it's because the Texas DMV potentially has consolidated record keeping whereas going to each Texas county court house records keeping has potentially more overhead and is a much larger project?
Changing a gender marker on a driver's license like most(all?) US states requires the presentation of a court order, the original of which is kept in each county's court records department. The Texas AG could theoretically request such court orders from each county in the state and get the same information. If Texas is anything like my state (CA) such records are accessible to the public unless sealed which is a rather uncommon practice(usually held for minors).
