Combine vinaigrette ingredients until well blended; set aside.
Place cucumbers in a colander over a plate; sprinkle with salt and toss. Let stand 20 minutes. Rinse and blot dry with paper towels.
Meanwhile, in a small bowl, combine honey and chili crisp oil. Spoon over salmon. Preheat air fryer to 360°. In batches, arrange salmon in a single layer in greased air-fryer basket. Cook until a thermometer reads 145°, 15-17 minutes.
Add avocado, lemon juice, green onions and sesame seeds to a large bowl with cucumbers; toss to coat. Divide mixture onto four plates with a piece of cooked salmon. Serve with vinaigrette and roasted seaweed sheets if desired.
