Standard legal fees for suing someone in the US are around a third of what you win, on a no-win-no-fee basis. So he sued for 3 million, he would have paid his lawyers a million if he’d won. So two thirds of a million to the other side’s lawyers is comparable.
Of course, all three figures are ludicrous, but the plaintiff started that by suing for 3 million.
And lawyers have a high list price to allow for the risk of not getting paid - both people who don’t pay and reductions made by the court, which is quite likely to happen in this case.
