Dumbledore was absent from the castle.

And he made it sound like the wards only alert him when a student has died. It's reasonable to expect them to warn ahead of time, after serious injury or something, but going by canon Dumbledore had no external alarm when Harry broke however many bones however many times on the Quidditch pitch.

Dumbledore placed a ward on Hermione that alerted him to any "hostile magic" or "evil spirit" that touched her. Someone either got very lucky, or knew about the wards.

And yet the explanation for the method of the attempted murder of Draco was that the slow cooling of his blood would cause his vitals to drop too slowly to trigger the wards until he died. Which explicitly relies on the common knowledge that Hogwarts DOES have wards that track the vitals of its students and that those wards are keyed to track sudden changes, and the removal of significant portions of the body would certainly constitute a "sudden change" in vitals.

So in the attempted murder of Draco, the wards were circumvented; in the troll attack, they were actively compromised.

Or the wards only detect sudden vital changes caused by hostile magics.

My grandparent is working on the assumption that Dumbledore is the culprit and would have had simple ways to make sure Hermionie doesnt die by mistake as a result of the attack he coordinated.

Ah, I see. I was also working on the assumption that McGonagall was correct; no reason Dumbledore couldn't say he was leaving, head to his office, sit back, and watch.

If it was him and he wanted Hermione to die, then he also had an excellent excuse to watch the battle with wards without acting on it, namely that he supposedly timeturned back after the fact and couldn't change anything.
