Do YOU think they purposefully made Ellie like Ellen Page?
I actually do. She looks almost identical to Page and much more like her than the actual actress who plays her. They chose an actress with a similar sounding voice. Her personality is very similar to that of characters Page has been known to play. It's almost as if Juno herself was thrust into an apocalyptic world. And her name is Ellie... Not to mention the fact that it was released in the same year as Beyond Two Souls which actually features Page. They also revealed Ellie to be gay (or at least bisexual) a year after the games release with the Left Behind story which just so happened to be released on the same day Page herself came out publicly. Now there had been rumors that she was gay and many well-known celebs were already aware of said fact so it couldn't have been too hard to figure this out and then incorporate it into the story. All that aside - Ellie is pretty much a walking Ellen Page character.
So what are my final thoughts? This is an outstanding game, but, yeah, I think they did rip-off her likeness. Many people thought it was her so they got the bonus of people believing Page was in the game and therefore drawing them in without having to pay her a cent. Ellen was reportedly frustrated by this which I can completely understand especially since she had her own game coming out that same year. But she never took legal action like most actors today would. I think she's far too nice and chill of a person to do that.
