1. Using a sharp knife, cut kernels from cobs and set aside, reserving cobs.
2. Heat oil in a Dutch oven or large saucepan over medium until shimmering. Add onion and garlic and cook, stirring frequently, until softened but not browned, about 5 minutes.
3. Add potatoes, broth, and reserved cobs and bring to a simmer. Cover and cook, stirring occasionally, until potatoes are nearly tender, about 20 minutes. Add kernels and continue to cook until just tender, about 5 more minutes.
4. Discard cobs, then transfer soup to a blender and let cool 10 minutes. Puree until mostly smooth. Strain soup into a large bowl, then stir in half-and-half, lemon juice, hot sauce, 1 teaspoon salt, and 1/2 teaspoon pepper.
5. Refrigerate until very cold, about 2 hours, stirring occasionally. Season with salt and pepper to taste and sprinkle with chives before serving.
