The Dossier isn't wrong. Ulfric is an asset to them. He is an asset to them because he is the leader of the Stormcloaks, and the Civil War is helping them as long as the two sides are fighting. The Thalmor want the war to keep going as long as possible to cause problems for the Empire. That is why they don't want either the Empire or the Stormcloaks to win.

The Thalmor have been an integral part of starting the Civil War, having pushed the Empire into throwing Ulfric and his militia into jail after the Markarth Incident.

Also the part about him being uncooperative is because he hates the Thalmor, they did capture him in the Great War and torture him. They even made him think that the fall of the Imperial City was his fault.
