unfortunately or not, TV series is canon, so you have to consider it, lol.

Or you prefer to kill some ovies, other characters and events from TV series in your fiction?

About topic: Well, only creators (plot scenarist or someone else, I dunno) know that. Did they leave intentional tease or not... Was it just tease or serious possibility?

Anyway, as you already know, my general position about such situations - characters don't have to immediately have a crush on other character if he/she is opposite gender and have the same species/size, especially when he/she appeared not so long ago and you have a little time together...
but - if I temporally put aside my position and look at this, trying to read Littlefoot's and Ali's personalities, ages, their small but so important trip, where everyone had a time to show their characters and behavior... I would say - there is small possibility, but I still think Littlefoot saw her as new best friends like his other friends. She actually was first not counting still hatchling Chomper. Of course Littlefoot was upset they had to move apart so shortly and for long time ahead.
I wanted to see more Ali's appearances in LBT, especially after Chomper's return in next movie, and I was sad she didn't appear, and when appeared - it was not enough time that is bad.
Let's see, if Ali returns in the future. Who knows, maybe some creators will leave new tease or hint about this.

Huh, btw, I want to tell here a small story from my very first watching LBT IV. As you remember, at the end of the movie, during Littlefoot's "memory sequence", there was a fragment of scene when Littlefoot and Ali played tag, where Ali touched Littlefoot's cheek with a nose and he stunned for a moment. And well, I somehow missed or didn't remember at all this moment in actual scene at the beginning of the movie, and it looked like Ali... ahem, well, at that time I jumped out of sofa with mind screams "WHAT??? She kissed him??? WHERE? WHEN? I don't remember this scene before! DID IT HAPPEN OFF-SCREEN??? :O".
Lol, I laugh each time I remember this.
By the chance, is there somebody who thought the same?
