Hades is just uncomfortable cause Percy beat the shit out of his army and had him at swordpoint. But there's no way he has any right to bear a grudge when he was the one who detained Percy. Plus, considering Percy vouched for Hades and his children in his wish, there's no way Hades won't show gratitude. As Poseidon says, even the Lord of the Dead pays his debts.
If that wasn't enough, Percy was one of the instrumental people in saving Thanatos, Hades's right hand in the Underworld, the god of death, so there's that. There's also the fact that Percy is super close with Hazel, who looks up to him like another brother. Bianca herself trusted Percy enough to leave Nico to him and again Percy was also the one who got Nico out of the jar along with Jason.
So I don't see why Hades would have a beef with Percy considering Hades sort of owes Percy for so many things. But I see why one might think so cause Hades has complex feelings when it comes to Percy given the things Percy has done and the stuff Percy knows.
Percy is one of the few people to know that Hades cursed the Oracle of Delphi. And the reasons behind it. I don't remember whether Apollo knows who cursed his Oracle but I am sure that won't go over well with either Apollo or any other Olympians; after all the Oracle is always under the sacred protection of the King of Olympus and Olympians themselves. So it's definitely quite punishable to curse the Oracle.
And if you remember the short story, the Sword of Hades where Persephone fucks up by going behind Hades's back and trying to create another great weapon for him and forces Percy, Thalia and Nico into a quest. The punishment for an Elder God forging another weapon of power is enough to incur severe consequences from the rest, especially Zeus and Poseidon. While Hades wasn't directly at fault, it was under his name that the weapon was being made. Thankfully, neither Thalia nor Percy snitched on what Persephone was upto and so only five of them knew. And if that got out, it might become very problematic for Hades.
Which is another reason why he has complicated opinions on Percy, a demigod to whom he either owes quite a bit to when it comes to his children and someone who knows things about Hades that he rather not have anyone know. But either way he definitely won't be petty to Percy in terms like the ones op mentioned, cause there's Poseidon to think of and Hades knows that Poseidon loves Percy enough to take actions like Hades banning Percy from entering the Underworld as a slight against himself as well. I just find it so funny that all of the Big Three have a very uncomfortable relationship with Percy. Hades because Percy knows some of his secrets and he owes Percy for everything he did for his children; Poseidon cause he is trying to be a better father and mend his relationship with Percy, Zeus cause he wants Percy dead so bad; like that so called all powerful God is so fucking hellbent on wanting Percy's demise, so paranoid and afraid of what Percy might do. I swear if Zeus saw half of what Percy did in Tartarus, he would sentence Percy to execution then and there and the war it would cause. I honestly want to see that happen just for the sake of it.
I like to imagine that Hades is real nice to Jason, yknow? Partly out of spite cuz he doesn't like Percy and partly to genuinely show he appreciates how well he treats Nico and looks after him. And I think that would make for some hilarious conversation like Jason goes "Yeah Hades is pretty neat I had to pop around a cemetery for a quest and he showed up out of nowhere, said he was just passing through, ended up helping me out and even bought me lunch" while Percy is just "he threw me in a dungeon once". ¯\_(ツ)_/¯
I mean we know Hades picks favorites and is capable of learning to be a better father/uncle sooooo.
Nico: Hey can I invite Will to our scheduled dinner next week?
Hades: I'm sure we can find an extra seat for him.
Nico: Can I also bring Meg?
Hades: Demeter would enjoy seeing her daughter.
Nico: Can I bring Jason?
Hades: Of course you can bring Jason.
Nico: Can I bring Per—
Hades: No.
