Peel/Slice the Eggs: Carefully peel the eggs, and slice then in half lengthwise. Spoon out the egg yolks in a bowl. Place the egg whites onto a clean dry plate or platter.
Make the filling: Remove half of the egg yolks and reserve for another use. Cut the avocados in half. Remove the pit. Scoop out the avocado flesh and place in the bowl. Mix the red onion, tomato, cilantro, sour cream, garlic, cumin, lime juice, and salt. Mash to make a smooth filling.
Fill the eggs: Use a small ice cream scoop to fill the egg whites. Alternatively, use a piping bag to pipe the filling into the egg whites.
Garnish the eggs: Sprinkle each deviled egg with paprika. (optional) Add a small piece of tortilla chip to each of the eggs.
