"Besides the transformation thing, are they just 'extra horny' just like most Incubi or do they infact go a little crazy, keeping in line with Lovecraft mythology ?"

I mean there isn't really that much information other that the entries are hyperbole and the chaos monsters even more so. They, being new to the scholar,  are meant to to convey a sense of "other". He has also said Mindflayer would get along well with other monsters. Even acting as marriage counselors for them. The entry Atalach-Nacha's husband changed backed to have a conversation with the scholar (the extra art was him getting sexually attacked by his wife that was upset he left her alone).

"And another question: would the returning of Chaos demons mess things up for the entire MGE world ? "

It's already mentioned that at this point they have monsterized and would most likely be limited to the same rules as the rest of the setting.

Just like the Atlach-Nacha:

"When this nest is completed, legend has it that it will bring about the end times. In the encyclopedia's world, the "end of the human world" means monsterization and transformation of the land into a demon realm, of course.

In the encyclopedia's world, only the ground immediately above their nests would turn into a demon realm, but suppose that they lived underground across the entire world, and their nests covered the entire globe, really the entire world would turn into a demon realm..."

It's unlear if they are going to be an actual breed of god-like monsters or monsterized gods like the Fallen God.
