Currently if you have your website to accept credit cards and process through paypal pro or the option to use paypal express.
The customer is required to enter a billing address even though paypal express will never use the billing address.
From the PayPal Express integration guide:
"When your customer selects PayPal as a Payment Method, for the best buying experience, you
should: Use JavaScript to hide or disable credit card fields and billing address fields, because
prompting for this information is irrelevant when a customer pays with PayPal."
