Comal County. No LLC, paid as a private citizen.
"Anyone who buys taxable goods and services that are stored, used or consumed in Texas from a seller who does not charge Texas sales tax owes Texas use tax." - https://comptroller.texas.gov/taxes/sales/use-tax.php
Above includes a link to the form to submit the use tax. After a lot of research, I was convinced that registering the aircraft in Texas triggered the Comptroller to check for payment of use tax and collect it with late fees, etc. YMMV.
