Explanation:

In the sentence "Ernesto de la Cruz paints, writes, or juggles when he needs to relax", the commas are used correctly in the series of verbs (paints, writes, or juggles) as the Oxford comma (or serial comma) is appropriately applied here to separate the items in the list. So no changes to the commas are needed.
