Is "Airman ga Taosenai" grammatical?


I've been listening to this memetic song for quite a bit, but recently I was
thinking perhaps the title could be inaccurate. Shouldn't it be "Airman wo
Taoserarenai"?

There are 2 points I have to make here:

One, たおせない means "to not beat/defeat" when the song clearly sings about not
being **able** to defeat Airman, which would be expressed by the negative
potential form of 倒せる: 倒せられない.

Two, the object is エアーマン, not the player, so エアーマン needs a を instead of a が,
right?

Am I on the mark on these two counts?

'Not defeat' is 倒さない, not 倒せない. 倒せない means 'not be able to defeat'. As for が
vs を, the potential form ('be able to', 'can') is traditionally used with が, I
think in either of the following manners: 僕にはエアーマンが倒せない, or 僕はエアーマンが倒せない, but
it's becoming more and more frequent to use it with を like this: 僕はエアーマンを倒せない.
