Talbot's chainsaw damage during untap

Is the damage done during untap considered to be from the weapon or it is enviromental damage?
The way that it is written, to me, it is evriomental since it not dealt during a strike and is worded like carrion crows.
Also reading 3.17 of the FAQ seems to reflect this.

It is weapon damage. That's why it is often paired with Mictlantecuhtli and Ambrosius the Ferryman because they are immune to weapon damage.

Ambrosius isn't immune to weapon damage. A Flamethrower would kill him.
But Talbot's damage does indeed come from the weapon.

"Environmental" only applies to damage dealt during combat (and is opposed to "from the opposing minion")

The source of the damage is equipment, weapon. I think that's the key factor here.

Correct hence LSJ said:

Yes. Talbot's Chainsaw is a weapon.
Damage from Talbot's Chainsaw is damage from a weapon.
