Heat the broth in a 3-qt. saucepan over medium-high heat. Add the tomatillos and garlic, bring to a boil, reduce the heat, and let simmer until the tomatillos are cooked through but still hold their shape, about 1 minute. Let cool slightly, about 5 minutes, and then carefully purée the mixture in a blender along with the olive oil. Pour the purée into a nonreactive 9x13-inch pan and refrigerate to cool quickly.
When the purée has cooled, remove the pan from the refrigerator and stir in the avocado, cucumber, bell pepper, onion, cilantro, and lime juice. Season to taste with salt and pepper. Refrigerate for at least 1 hour and up to 4 hours. Before serving, taste and adjust the seasoning with more lime juice, salt, and pepper, as needed. Spoon the gazpacho into individual serving bowls or mugs.
