[Avatar] Does Toph have any way to defend against a flying jump-kick?

Probably, she would detect them jumping off the ground, and as long as they can't change directions mid-air, she could just throw up some rocks in their face. Which is why she had so much trouble with Aang-he could change directions mid-air without touching the ground, so she had no idea where he would be going. She's also got a pretty great sense of hearing, so it's not like she wouldn't hear them jump up in the air at her. 

The only time she's really struggled are:  

-Against Aang, who was an airbender and she couldn't sense his location (Also almost nobody has any idea how to fight airbenders)

-With metal before she developed metalbending

-Unusual surfaces (she can't see as well when walking on sand, and she had a hard time crossing the ice bridge since she's walking blind as well). 

-Underwater or in the sky, since she's not near earth and can't see much. 

Otherwise, she's almost unstoppable without resorting to trickery or overwhelming numbers.
