"forced to overpay" is a weird, kinda Muskist-flavoured way of putting it. He just overpaid. He decided on a price, made a bid, reached agreement and concluded the deal, all entirely freely and of his own accord.
That he then wasn't able to bullshit his way out of the contract shouldn't be more than a footnote, it's just normal process with court involvement only because he thinks he's special.
I wonder how detailed your prompt was for this? Did you just say something like "apply a my little pony metaphor to the results of the recent Spanish election" or did you explain the whole situation to the model explicitly?
