So I'm guessing it also wouldn't take into account abilities such as Warstorm Surge or Omnath, Locus of Rage's second ability?

Yea, it doesn't take those abilities into account. Since they only trigger when the creature is on the battlefield, it unfortunately won't work.

Thank you for helping refine my Omnath, Locus of Rage build.

An ability is, by definition, not a spell.
A spell is a card, or a copy of a card, on the stack. Every card type except lands can be cast as a spell, whether from your hand or, in some cases, from your graveyard, your library, exile, or the command zone.
Whenever a creature, artifact, planeswalker, or enchantment spell resolves, it becomes a permanent (objects on the battlefield are permanents).
Permanent spells generally don't do much on the stack. Even permanent cards that do something while on the stack (such as Ulamog, the Ceaseless Hunger) do so through triggered abilities, so the spells themselves won't do anything.
Hostility's ability only triggers if the spell is the source of the damage (e.g., Shock).

Every card on the stack is a spell. Cards in the graveyard, libary, battlefield etc. are not spells. Therefore, Hostility doesn't work with creatures on the battlefield.
However, as long as a creature is on the stack, it is considered a spell.
