"The term is a reference to Vladimir Nabokov's book Lolita, in which a middle-aged man becomes sexually obsessed with a twelve-year-old girl.

Loli is a sexual term. You can argue whether OP meant it in a sexual way or not, but the term Loli refers to erotica.

Not inherently it doesn't. The term lolicon does for sure though as it means lolita complex. Pretty sure at this point loli is just an objective statement about physical appearance with no implied connotations.
