Heat 2 tablespoons olive oil in a large Dutch oven over medium heat. Add chopped celery and onion; cook for 3 to 5 minutes or until softened. Stir in 1 teaspoon garlic; cook for 30 seconds.

Stir in 1 tablespoon steak seasoning, chili powder, cumin, hot sauce, and Worcestershire. Stir in vegetable juice and kidney and pinto beans. Cover; simmer over low heat for 12 minutes.

Heat 1 tablespoon olive oil in a 10-inch cast-iron skillet over medium-high heat. Pat steaks dry with paper towels; season with remaining 1 tablespoon steak seasoning. Place steaks in skillet. Cook for 6 to 8 minutes for medium-rare doneness (135°), turning halfway through. Transfer steaks to a clean cutting board; loosely cover with foil and let rest for 5 minutes.

Place parsley, cilantro, and remaining 1 teaspoon garlic in a food processor or blender. Cover and process until finely chopped. Slowly add remaining 2 tablespoons olive oil. Continue processing until smooth, stopping occasionally to scrape down sides.

Slice steaks across the grain. Ladle chili into serving bowls; top with steaks slices and parsley mixture. Serve with sour cream and garnish celery leaves, if desired.
