Preheat the grill to medium-high heat at approximately 400°F (200°C).
In a small mixing bowl, combine Greek yogurt, minced garlic, 1 tablespoon lime juice, honey, and a pinch of salt; whisk until smooth and refrigerate.
Place corn ears on the grill and cook for 8 to 10 minutes, rotating occasionally until kernels are lightly charred; remove from heat and slice kernels off the cob once cooled.
In a medium bowl, toss the charred corn kernels with diced avocado, red onion, chopped cilantro, and the remaining 1 tablespoon of lime juice.
In a separate bowl, coat the shrimp with olive oil, smoked paprika, garlic powder, salt, and pepper.
Thread shrimp onto skewers or place directly on the grill grates, cooking for 2 to 3 minutes per side until opaque and firm.
Distribute the cooked grains evenly among four serving bowls.
Top each bowl with a portion of grilled shrimp and the avocado corn salsa.
Drizzle the prepared creamy garlic sauce over the bowls immediately before serving.
