Not lichess, but Alireza Firouzja (World Rank #3) was banned from chess.com when he was younger.
This has turned into a bit of an urban legend. The automated system flagged him based on both his rapid rise in rating and reports from several verified titled players.
On inspection by a human, he was cleared.
Danny exaggerates when he tells the story cause it's a funny anecdote.
This was also a very old version of the anti-cheat like you mentioned. Personally, part of the reason I prefer chess.com is their much better cheat detection than Lichess.
