Rock and Seinfeld were clearly willing participants. Leno, too, but I don't think that was a particularly unsympathetic portrayal of him. As for Letterman, I saw nothing in the episodes that would have required his participation or permission.
What strikes me this season is that the show has really established its "surrealistic sitcom" style. There's no attempt here to show how things really happen, but CK gets to the heart of real-life issues by creating live-action vignettes of how things feel when they're happening. Very subtle, and easy to mess up. And impossible to explain to people who aren't already onboard.
