Except there are bows and crowsbows that can fire hundreds of feet into the air, not to mention with all of the pollution in Mordor from making all of those weapons, armour, and siege machines, the eagles wouldn't be able to fly very high, let alone the fact that the air is partially poisonous to them, there are also plenty of machines that could easily have take the eagles down like ballistas.
Mmmm....no, not really. In most cases, even with todays best crossbows, the maximum effective "kill range" is roughly 40 yards, give or take.
Firing up into the air, that distance would be drastically shortened, due to gravity. So, if the eagles were to fly above three hundred feet, they'd be unreachable.
As for the pollution, that didn't stop the eagles from flying
to the top of mount doom, even as it was erupting. So that point doesn't make much sense.
Ballistas, while providing the range needed, would be hard to move and aim quickly and accurately. Ballistas were used as siege weapons, not fast-acting anti-air weapons.
I'll explain more below:

Not sure about the bows but they for the rocks they had catapults, hell for throwing rocks they had trolls.
I'm not sure how they are a plot hole exactly, could you explain?
Because, at worst, using the eagles to fly to Mount Doom presented the same amount of risk as sending in two small hobbits....
on foot and by themselves....into Mordor.
At best, it could cut the travel time down to days, even hours, and circumvent almost the entire orc army.
The point is, if the council at Rivendell had wanted to take the best, least-likely-to-fail course of action, they would have sent their best people with the eagles.
(though, that would have made for a much less dramatic, less compelling story, so...)
Again, it's a plot-hole that's been present since the first printing of the novels. It doesn't necessarily detract from the story, but it is still a curiosity. People can admit to plot-holes and contrivances in their favorite stories without losing their love of the material.
Even with realizing some of the failings in the plot, The Lord of the Rings trilogy remains one of my favorite stories.
