All government, including state and local, is prohibited from interfering.

No, the text clearly says Congress, not "the legislature", or even more broadly "the government".
Where this comes into play is via the second sentence of Amd 14's Sec 1:

No State shall make or enforce any law which shall abridge the privileges or immunities of citizens of the United States; nor shall any State deprive any person of life, liberty, or property, without due process of law; nor deny to any person within its jurisdiction the equal protection of the laws.

Then show how the order is a violation of the TX constitution regarding religion and there you have it.
