Do most of Lilith's works have around the same word count, or do they vary wildly?

That depends on the era. Over time, eroge in general started getting padded out more and more, to increase their perceived value. By 2014, your average Lilith game was about 12 000 - 15 000 lines, in contrast with older games, which would be 6500 - 9000 lines. There are a few exceptions, such as TA3 (30 000), TY2 (23 000 without the gacha scenes I added), and Chronos (9500 lines, despite being released in 2014).
