Technically speaking these are not lolis as you put it, they're just a small race of creatures. That's like saying hobbits are loli, because they are small creatures therefore they must be children.
The word "loli" has been appropriated and reappropriated multiple times.
At first it was from the story Lolita, a story about a horrible, fictional pedophile.
Which was apparently picked up by Japan, where for some reason it was used for the word pedophile, instead of actually the word pedophile.
Since then, it's gone through all sorts of reappropations and changes in the West and Japan.
The Lolita fashion subculture where people dress in frilly children's dresses. It has little to do with the novel, or pedophilia.
At one point it meant an age, loli was a young girl, and a lolicon was a pedophile who liked young girls. Like a gender specific pedophile.
But after years and years, words evolve and change. The word "gay" used to mean happy.
At this point in time the word "loli" seems to describe a body type more than anything. It means someone who looks like a young girl, not necessarily someone who is a young girl. This is the mainstream definition in the English speaking world, at this point. And is arguably so in Japan, as well.
In fact, the definition of "loli" has become so broad at this point, I cannot even so much think of a single flat chested female anime character in all of anime, that isn't commonly referred to as a "loli". Even Black Rock Shooter has been called one. And she's pretty tall.
The Elin have the body of a young girl, even though they're characterized as being adults. So calling Elin lolis fits with the modern definition and usage of the word.
The Lalafell are also stated to be adult, and act that way. But I think most people familiar with the term would still call them lolis.
