The DDAL DM Guide states, for resurrection:
Death. A character who dies during the course of the adventure has a few options at the end of the session (or when arriving back in civilization during the adventure) [...]
No matter the means of death, bodies (and its possessions) are considered recoverable by friends and allies unless otherwise specified.
So, yes, she can be resurrected during the adventure if she was brought back to city. She can also be resurrected even if not - just wait for the end of the session.
The text then proceeds to describe what the player can do - paying for being resurrected, the party paying for it, the faction doing it as a favor or simply creating another 1st level character. These are also important to log, since the character is losing some gp there.
About the ToA Death Curse:
"Any character can choose to be rid of the curse by: [...] Waiting It Out. Alternatively, characters can wait until others have done their dirty work by retiring from adventuring until the release of Season 7’s Tier 3 adventures (January 2018), or by starting any Tier 3 or 4 non-hardcover (non-DDHC) adventure, and resuming adventuring following Acererak’s defeat. A character choosing this option can’t play Tomb of Annihilation, or any Season 7 Tier 1 or 2 adventures—with or without a surrogate; these doors to adventure are forever closed to them."
Thanks to @T.J.L. for the correction - the curse is still active for ToA and S7 T1 and T2 adventures. When she "Waited it out", she got rid of the curse (as stated in the beginning of the text):
Any character can choose to be rid of the curse by [...]
As the curse no longer affects her, she can be resurrected, but, as from the emphasized part, she won't be able to play ToA, S7 T1 or S7 T2 adventures with that character.
