Maybe this wasn't outright said, just implied in the quest, but most of those answers seemed to be solved with the reveal that Jas was working through Sliske....
"Lore is pretty bad too. How did Sliske even build that maze or 'turn off' divinity?"
As you say later, Jas - either directly, or through Sliske (telling Sliske how to use the stone to do that).
IIRC, all the pacts have been made in all playthroughs, and it's hinted at(or it's supposed to be) that Zaros, at least, has been doing this with all the Gods. (Hinted at through looking at the pact in CoM, which Zaros purposely put Zamorak in a position where he had to agree to it - the inference is that the situation was intentional and that it was likely he would try that with more Gods then just Zamorak -why put all your eggs in one basket?)
The real surprise was Seren having done similar things, she's clearly learned from her past and from Zaros...
In terms of the Pacts, the only difference between playthroughs is which pact is actually evoked in the end (if any).
Saradomin's daughter's existence was hinted at back in Hero's Welcome, just wasn't outright stated to be an emotional weakness (as opposed to some Kryptonite kind of thing, which I at least am grateful for). As for the exact relation to Saradomin, the only thing that was confirmed is that emotionally , Saradomin loves (presumably her?) as a daughter emotionally, she may not be an exact blood relation - but then again, who knows?
Icthlarin's backstory is that he was a dog who was turned into a God - that is hinted at in the Dream of Tumeken text, and is also a staple of several mythologies, I don't know why you'd say it was laughable. It was played for comedic effect by Sliske in the maze, but that's meant to be a character defining time for the player- what do they do when something once powerful becomes helpless?
