If a Half-Orc with the Toothy Racial Trait were to make a single bite attack (and no other attacks), would the bite get the benefit of 1.5x STR since it's her only natural weapon or would her iterative attacks count as "multiple attacks"?
If a creature has only one natural attack, it is always made using the creature's full base attack bonus and adds 1-1/2 times the creature's Strength bonus on damage rolls. This increase does not apply if the creature has multiple attacks but only takes one. If a creature has only one type of attack, but has multiple attacks per round, that attack is treated as a primary attack, regardless of its type.
What if she was under the effects of haste? Would the second bite attack make both of her attacks 1x STR?
