The statement, if incorrect, would not by itself make a will invalid. Bit it could possibly be some evidence that she did not have testamentary capacity when signing the will.

I doubt that the mere recitation of the wrong county in and of itself renders the will invalid. A judge will, if a contest is filed, will look to the totality of the circumstances such as whether perhaps it was a scriveners error in that the remainder of the will and the circumstances surrounding its execution indicate that the testator was of sound mind and not subjected to undue influence.
It would be best to retain a probate attorney in Parker County who can review the will and explore whether a Will contest should be considered.
Unless mom was delusional or mentally incapacitated and actually believed she was somebody else who lived in Hood County, I'm going to guess that the lawyer's word processor screwed up and inserted someone else's language in the document. To err is human, to really screw things up, you need a computer. And I betcha that's what happened here.
This is not legal advice. I am not your lawyer. You are not my client. You cannot rely on my response to your question. My response to your question is probably worth exactly what you paid for it. You don't get to sue me for anything. If you'd like to sue me, well you have to hire me first.
I vote that that would not make the will invalid
