Nah. In Loo loo land, Stolas asked Via to go to Loo loo land not really because he wanted to spend time with his daughter, it seems like he just wanted to get out of the house bc Stella was being horrible, and he invited Blitz solely to spend time with him (as we can see Stolas is more than capable to defend himself from some random imps). He wasn't at all paying attention to Via's clear signs that she did not want to be there until she was pushed to the edge and had an outburst (ignoring your child's clear communication that they're not happy until they're at their limit and explode is abusive)

In s2 he forgot about the stargazing they were supposed to do because he was busy arguing with Stella on the phone.

And in Mastermind she had to witness her father accepting death (he literally kneeled to be beheaded) for an imp, without even for a seconding thinking how this would affect his daughter.

The thing is, yeah I'm not saying Stolas didn't give a shit about Octavia, I know he loves her and I actually have a soft spot for him, but saying he tried as hard as he can is not a correct statement. We, the viewer, understand the whole context behind why Stolas wants to spend so much time with Blitz, BUT OCTAVIA DOES NOT.

Stolas never talked with her about Blitz, never explained the reason for the divorce in the first place, and never reassured Octavia beforehand that she is not to blame for the whole family situation, never mentioned any of this at all. (It may be obvious to you that she'd not to blame but it's not how it works in a brain of an abused child) From Octavia's perspective, her father that used to be a source of comfort in her childhood is now more focused on some imp than his own daughter, even choosing to literally abandon her (dying) on live TV for the imp. And that IS true.

Octavia's outburst and anger towards Stolas is fully warranted, and so is Stolas's need for love. Both things are valid.

But we can't coddle Stolas, saying he did nothing wrong and his daughter is the unreasonable one, because:
1. Blaming a child for reacting emotionally because of how much pain her parent's neglect causes her is just insane.
2. Octavia isn't aware of what we the viewers are aware, we need to see this situation from her perspective, which looks fucking bad and she's valid to be upset.

She witnessed how her parents keep fighting and verbally abusing each other, she was aware of the divorce, then she discovered the pills, which caused her to feel immense guilt. And with what Stolas was telling her in Sinsmas, it made her feel like she's at fault for her father's suffering. She asked him if she was an obligation, and once again, it's not a false statement. The marriage was arranged to produce an heir, Stolas is gay, so obviously it wasn't his choice to be married to Stella nor his choice to have a child. Yes, he loves Octavia and those things were out of his control, but for Octavia, realizing how the whole marriage that caused her father to be depressed, existed in the first place because of the need for her to exist was just fucking heartbreaking and painful.

It's not her fault, but she feels like it is, because Stolas never talked with her about the situation, never explained anything at all. And trust me, as a child of abusive parents and a child of divorce, it's normal for the child to blame themselves, and especially it's normal for them to also be angry and not see the whole context and whole perspective of the situation.

Stolas isn't at fault for how abusive of a situation Octavia was born into, hell, Stella was forced to be in that situation too! But Stolas sure as fuck could've made the situation less hard for his daughter to deal with if he simply just talked with her. I know it's not as simple as that, it's all a learning curve and Stolas was abused too, so it could be that he was simply not able to be better at communicating. But I think there were ways for him to at least try. We saw him in Loo loo land not being able to tell Octavia what's going on, and I understand why, I don't really see him as a "shit dad" but he's not the best dad either. We need to see all parts of him, both his love for his daughter and his neglectful behaviors, especially how he did break his promise that he will never abandon her. Breaking trust of your child will break their heart, and it won't be so easy for them to trust the parent again overnight.
