In a bowl, toss the shrimp with olive oil, chili powder, garlic powder, smoked paprika, onion powder, salt, and black pepper until evenly coated.
Heat a large skillet over medium-high heat. Cook the shrimp for 2–3 minutes per side until pink, lightly charred, and cooked through. Remove from heat.
In a medium bowl, combine the diced mango, red onion, jalapeño, cilantro, lime juice, and salt. Toss gently to make the mango salsa.
In a small bowl, whisk together the mayonnaise, Greek yogurt, sriracha, lime juice, garlic powder, and salt until smooth.
Divide the cooked rice between serving bowls.
Top each bowl with shredded lettuce, cooked shrimp, avocado slices, and generous spoonfuls of mango salsa.
Drizzle with the lime-chili sauce and garnish with fresh cilantro and lime wedges.
Serve immediately while fresh.
