Pat the shrimp thoroughly dry with paper towels. Sprinkle the cornstarch on a baking pan. Scatter the shrimp over the cornstarch, and shake the pan to evenly coat the shrimp.
Arrange the shrimp in the basket and spray with an even coating of extra-virgin olive oil. Place into the air fryer. Select Air Fry, and set the time to 8 minutes and the temperature to 350°F. Select Toss Reminder and press Start/Stop.
When alerted, shake the basket and spray with additional oil if needed. Replace the basket to finish cooking.
While the shrimp are cooking, combine the chili sauce, lime juice, lime zest, soy sauce, and Sriracha in a medium bowl, and set aside.
When the shrimp are finished, transfer to the bowl with the sauce, and gently stir to coat. Transfer to a serving bowl, and top with the sesame seeds, scallions, and cilantro.
