Technically, Lovecraftian lore is fictional. However, it's a case similar to how Kojirou Sasaki doesn't actually exist but a close-enough swordsman was summoned as him. Yog Sothoth doesn't actually exist, but there actually does exist alien beings very similar to those in Lovecraft's stories, in this case one known as Sut-Typhon responded to the summons for Yog Sothoth.

Basically, this way Type Moon can both use the mythos while not being bound by it, so their versions can be defeated by Servants or have substantial differences from the ones in Lovecraft's lore. Also, it ties into the overarching powerful alien threat being introduced in recent Fate works such as Velber from Fate/Extella.
