Is this game considered part of the main series or a spinoff?

Depends on the argument you are trying to do. For example:

- This game is a big flop from critics!

Answer: doesn't matter because it's a spin-off

 

- Aonuma must have developed a real sequel or a real mainline game

Answer: It's a mainline game. It has "The Legend of Zelda" in the title

Actually I don't see how anyone can argue that the game is a mainline game.  Link and Zelda are both absent from the game, and the plot is so out there, no reasonable person would consider it part of the main canon story.  It is, through and through, a spinoff title.
