Going to beat the record of the Robert E. Lee
Well, technically he's committed statutory rape numerous times...I found it on a podcast from someone going under the name "That Creepy Reading" who claimed to have done an hour long interview with Robyn, he names the doctor. In the comments claims he could never put the interview on youtube because of the extreme content, so was skeptical about it .
But later excerpts of the interview appear on "John Kricfalusi: An Open Secret" in which "That Creepy Reading" is interviewing Robyn , after the release of Happy Happy Joy Joy documentary her voice matches the audio, so assumingly the hour long interview exists and is real. Also matches up with earlier posts of big bowls of psychiatric pills being at Spumco for anyone to eat like candy. The podcast is below, it's slightly painful to listen to because the people discussing everything him are pretty clueless, he mentions the doctor at 7:48. Also another thing he mentions at some point in the podcast that John K has been involved in quite a few rapes which he claims to uncovered quite easily.

What you linked to is not the part of the interview that mentions the doctor, but I should note that the guy got his facts fumbled. The "pedophiles and enablers" all worked at Spumco, not Nickelodeon, and were all enablers - if we're thinking about Eddie Fitzgerald, Mike Fontanelli and Steve Worth, who have to be the guys he's talking about. I've never heard of them being pedos...
Then again, Eddie once worried he was going to molest his own pre-teen daughter...
