Why are the item modifiers stats hardcoded?

Is there no way to edit those or add new ones (other than the price modifier and rarity)?

Nope. There are plenty of unused item modifiers, so you can script in other effects based on item modifier, but it won't have an effect in combat unless you also check for the modifier in the troop's inventory before transferring it to agent slots and check for that in a ti_on_agent_hit trigger to increase damage or do some fancy stuff with it.
