Seems unlikely. VPNs have far too many legitimate uses. How many people are on VPNs for work alone?
I also don't think the law in Texas is written against the consumer, e.g. it doesn't say it's illegal to view porn if you haven't shown an ID. Rather, it's levied against the distributor to say it's illegal to show porn to someone you haven't age verified.
So it's not like the act of using the VPN to circumvent this would be criminal.
