Legends Arceus was ultimately there to expand upon the lore of Sinnoh's mythos, which mostly dabbled in the nature of the relationship between Man and Pokemon as well as Arceus and the gods who shaped the world.
But you can't really go back to depict Kalos' history because its history is primarily focused on an extremely grisly war founded on countless bloody deaths, Pokemon being treated as expendable weapons and the suffering of many, and the absolutely miserable state everyone would've been in after the Ultimate Weapon's firing and culmination of that sheer degree of death marked the end of the war.
