Add the cottage cheese to a small food processor. Pulse until completely smooth and creamy, creating the base of the dip.
Spoon the blended cottage cheese into a mixing bowl. Add the Greek yogurt, chopped pickles, pickle brine, white wine vinegar, fresh dill, fresh chives, garlic powder, onion powder, and salt.
Stir thoroughly with a spoon or small rubber spatula until all of the ingredients are evenly incorporated. Taste and adjust the salt or white wine vinegar as desired.
Finish the dip with a light drizzle of olive oil, additional diced pickles, chopped chives, and freshly ground black pepper.
Serve with crackers or fresh vegetable sticks, such as cucumber, celery, carrots, or sliced bell peppers.
