That is simply one person's opinion on Tumblr. It is not canon and probably will not be canon on the show.

Now I will say that Leni is always smiling and is generally a happy girl. She would've continued smiling while brushing her hair no matter what Lori could've said. She could've said "Poppity-Pop-Pop-Pop-Pop" and Leni would've kept the same expression. This means absolutely nothing as to her sexual identity.

As far as we know right now, Luna is the only person who is canonically LGBT. You are fine to think that Leni is because it's your life and people are probably going to draw Luan with Maggie for the rest of time and there is nothing I can do to stop it, so keep thinking that. It is perfectly fine.
