Step 1
Heat 3 Tbsp. oil in a large heavy pot over medium heat. Add celery roots and cook, turning frequently, until golden, 8-10 minutes. Add butter and a large pinch of salt. When butter begins to foam, reduce heat to medium-low. Add herb sprigs, coffee beans, if using, and 1 1/2 cups water. Cover and gently cook, adding more water by tablespoonfuls if pan is dry, until celery roots are very tender, about 1 hour.
Step 2
Remove herbs and coffee beans (if using) from pot and discard. Baste celery roots with buttery juices in pot. Remove from heat. Transfer celery roots to a cutting board, slice in half through stems, and place 2 halves on each plate.
Step 3
Meanwhile, very gently warm buttermilk in a small saucepan over low heat (it will break if warmed too much). Squeeze in a few drops of lemon juice and add remaining 2 tsp. oil and a pinch of salt to make a loose sauce. Spoon sauce around celery roots on plates. Garnish with olives, drizzle with oil, and squeeze a few more drops of lemon juice over each.
