Do casinos have regular Texas Holdem’?
Any casino with a poker room has Texas Hold'em. In many it's all they have. Hard to find Omaha or any other game sometimes. Not all casinos have poker rooms, of course.

You never play hold em against the dealer. Most have a poker room.
A lot of casinos have poker rooms. and I have never seen a poker room that does not have Texas Hold'em. Since you asked about Oklahoma here are some casinos that have poker rooms in Oklahoma: https://www.worldcasinodirectory.com/oklahoma/poker-rooms You should check the websites for the individual casinos to see if they allow players under 21. Since you live in Illinois, here are some poker rooms in Illinois https://www.worldcasinodirectory.com/illinois/poker-rooms
EDIT: I know casinos have Texas Holdem’. I’m specifically looking for one that has player vs player tables. If you know if there are any in Oklahoma, please list the name. Looking to start my drive ASAP!!
