I feel like your comparing apples and oranges there. Hollyhock was looking for some kind of self-fulfillment with regards to her parent quest. And she had no reason to suspect that she came from a complete trashfire mess of a family while doing so.
With this, it's more of a matter of "How much do I trust Bojack now knowing these things?" You could argue that this was a random stranger who might be lying, but realistically speaking, the way pete acted and said this things, with no real gain to be had for himself, it was obvious he was saying what he was saying out of genuine belief. He was inaccurate in some stuff, but the important things (Bojack being the responsible adult who fucked up) are right and Bojack wouldn't be able to disprove the tiny details he got wrong anyway. But just because she is willing to find her family in another state, it isn't the same thing as talking to her potentially dangerous and abusive brother.
And ultimately, it's kind of a moot point. We basically know what would happen. He'd just do what he always does and have his "I'm so sad and sorry" song and dance and beg Hollyhock's forgiveness and she'd be super uncomfortable with it.
All that said, I do agree that I wish Hollyhock had talked to him about it. Not because I think it'd have made a real difference, but it'd be a bit more honest and maybe fair. Like, Bojack kept trying to push into Hollyhock's life because he was trying to be supportive and that she was retreating into herself. He might have given her the space she needed to figure things out more productively if he just knew what was really going through her head and what she judged him for.
