I see what you're saying. First off, yeah stuff like time is off-limits.
For the air thing... altering air in that way is definitely outside of her abilities. Hmm... I'd say that big structures and components of nature (like air) have very powerful natural resistance. As i mentioned before, i could imaging her un/sealing air in some way, but only by very tiny amounts, not close to being automatically lethal or anything like that. But like with the other examples, if there's some kind of anomaly that changes the air in some way, she can run with that and use it to further mess with things. Like the hole example: she wouldn't be able to just create a hole in the ground out of nowhere, it's just that if a hole were created by something else, she can expand or reduce it.
