It's probably because there aren't enough web novel volumes.* Alternatively, they're still testing the waters with how profitable/popular LH is after Mamare's scandal.
* Mamare has written at least two volumes beyond what he's posted online and theoretically, the anime team could've repeated S2's situation and worked off Mamare's notes to pad out enough content for 24 episodes. Of course, considering the mixed reactions to S2, going the safer route and sticking to 12 episodes is probably a better idea.
