Not really unique to chatbots. Here's a couple of entries from the D.O.S. (which is apparently pay walled now? Turns out the top result is a site by a grifter completely unrelated to John Koenig).

Anecdoche

n.

a conversation in which everyone is talking but nobody is listening— instead merely overlaying words like a spoken game of Scrabble, each player borrowing bits of others’ anecdotes to build out their own, until we reach a point when we all run out of things to say.

From anecdote, a short and often amusing account of real-life events + synecdoche, a figure of speech in which a part stands for the whole. Pronounced “uh-nek-doh-kee.”

Anechosis

n.

a state of exhaustion with continually being told what you want to hear, whether by marketers pandering to you or acquaintances afraid of causing offense; the longing for someone to have the heart to finally call you out on your bullshit, challenge your long-held assumptions, and push you to become a better person—which would be a far deeper kindness than trying to live and let live.

From an-, against + echoes. Pronounced “an-uh-koh-sis.”
