Urgot could be considered as a good counter:

Passive mitigates damage done by Darius, allowing for better dueling.

Has good harass, due to being ranged. Can also farm safer than melee champions. Corrosive Charge + Acid Hunter's take a good chunk of health from very large range.

Can kite effectively with his W. It also doubles up as a shield.

Ultimate won't protect him when he is nearly dead due to Darius having true damage, but it can set up ganks in his lane much easier, due to Darius lacking any escape mechanisms.
