AI Overview is still 'yes, and'-ing completely made up idioms despite Google's best efforts to restrict it

Anyone studying a second language will tell you that learning idioms is often a stumbling block. I mean, just take my mother tongue, British English—'raining cats and dogs', 'on it like a car bonnet ', 'Bob's your uncle, Deborah's your aunt'—I mean, what bizarre fairytale creature would even talk like this?

Because idioms spring up from rich etymological contexts, AI has a snowball's chance in Hell of making heads or tails of them. Okay, I'll stop over-egging the pudding and dispense with the British gibberish for now.
