On behest of Sam clears throat:
No he didn’t. In fact, she captured him in Outland, then his cohorts freed him. Remember that mission in WCIII where you fight over his cage?
The event you’re referring to, when she wound up in the Warden’s Cage, wasn’t Illidan himself. He literally threw an army of fel orcs at her first to tire her out. Then fired a shadowbolt from his vantage point in the sky to knock her out. They didn’t fight.
Literally never happened. Maiev and Illidan have only directly crossed blades once in Warcraft. And she killed him.
Her wardesn aren’t her.
As someone who has Maiev and Illidan lore memorized, it’s far from the truth.
