they had around 2750 level points to use for Nazarick as a high rank guild base, and they bought additional points with real money.

Even then, they made a LOT of NPCs for the dungeon. And at some point they had already made enough for the defense of the dungeon. However, a lot of the guild members were role players(Ainz as well). As such, they also created a lot NPCs for roleplay purposes. Such as the 41 maids, the battle maids, the Five Worsts(who aren't built for combat in the least), and many more. Same for the librarians actually. The library is on the 10th floor, yet it has several custom made level 80minimum(since they are of the Overlord race) NPCs acting as librarians.
