Heat grill to medium-high. Rub tri-tip with 1 Tbsp oil, then paprika and ½ tsp each salt and pepper.
Grill, turning occasionally until browned on all sides and cooked to desired doneness, 18 to 25 mins depending on size of tri-tip. It's medium-rare when instant-read thermometer inserted into thickest part of meat registers 55℃. Transfer to cutting board and let rest at least 10 mins before slicing.
Meanwhile, in mini food processor or blender, pulse parsley, basil, capers, garlic, mustard, honey, ¼ tsp salt and ½ tsp pepper until finely chopped. Add remaining 3 Tbsp oil and pulse to combine. Serve with steak.
