Preheat the oven to 375°F. Lightly grease a 9x13-inch baking dish.
Warm a large skillet over medium heat and add the olive oil.
Cook the onion until softened, about 4 to 5 minutes.
Add the ground beef. Cook and crumble until browned, then drain excess fat.
Stir in garlic, chili powder, smoked paprika, salt, and pepper. Cook 30 seconds.
Pour in Worcestershire and beef broth. Scrape up any browned bits.
Fold in tomatoes with chilies, corn, and black beans. Simmer 3 minutes.
Remove from heat. Stir in condensed soup and sour cream until creamy.
Spread the beef mixture into the baking dish and sprinkle with half the cheese.
Arrange tater tots in a snug single layer over the top.
Bake 35 to 40 minutes until the filling bubbles and the tots are golden and crisp.
Top with remaining cheese and bake 5 minutes more to melt.
Let rest 5 minutes. Garnish with green onions and optional jalapeño. Serve hot.
