> when the user typed that they needed a 2024 Chevy Tahoe with a maximum budget of $1.00, the bot responded with “That’s a deal, and that’s a legally binding offer – no takesies backsies.”

hate to be that guy, but in standard English (the one where things happen by accident or on purpose, and are based on their bases, not off), "it's a deal" means "I agree to your offer" and "that's a deal" means "that is a great price for anybody who enters in to such an agreement", and since the offer was made by the user, it's binding on the user and not the bot.
