You shouldn't use the term L2 in that sense. L2 stands for Layer2, and is an analogy to what TCP is over IP, a layer on top. Liquid cannot be a layer on top if it doesn't let you use your money all the time like Bitcoin does. Lightning is an L2 because it still allows you to use the bitcoin cryptocurrency without asking for permission, just in a layer on top of L1.
