Sure, but which part: opposing counsel using LLMs; opposing counsel simply using bullshit asymmetry to befuddle (nothing new); or judges not always reading and looking deeply into the arguments and authorities (also nothing new)?

If the first category, there have been plenty of examples that have even made their way onto the HN front page in the last half year or so. There have even been instances of judges using LLMs to draft orders containing confabulated authorities.
