Ah then, just go buy any of the training tools like GTO+, GTOBase, Vision(by run it once), GTOWiz, PLOMastermind tool by Jnandez etc. They are essentially coaching software to learn the game(powered by a solver) and a ton of them have a practice section where you can play against an AI. One of the earliest Poker solver devs Oleg Ostroumov made this back in 2013 or so: https://holdem.olegsolvers.com/ . You can play with that.
On a side note, he also wrote about his story of building the first productized solver here:
Oleg's solver is fantastic, thank you! It's only for heads up, though.
I'm still surprised by the difference with the chess world where all the strong engines are free and open-source. Maybe poker is less attractive to developers, or maybe poker devs are simply more inclined to make money (which I completely understand!)

FWIW, this is a fairly
recent thing in chess (within the last decade). Before 2015 or so closed source commercial engines were better than open source options.
