Not everthing is ai and some are just edited. But by just batting an eye on the heroines main portraits you can see they are ai.
In every scene the chars have the same lighting reflex on the hair even if it is dark, this reflex was very common and is still kinda common in ais, another thing you can perceive is the ears they are incosistent. Idk why people see this as an attack, this game made a good use of ai. Ai games cannot be sold outside of japan in dlsite so it makes sense to hide the ai use in a translated game.
