Deep vein thrombosis (DVT) is unlikely to cause strokes, as DVT causes clots to form in the venous system, while strokes involve clots in the arterial system. Clots from veins are more likely to get lodged in the lungs (pulmonary embolism) than pass across the lungs into arteries.
The higher prevalence of strokes in COVID patients isn’t fully understood, but might be due a generally increased inflammatory state in the body, with complement (a cascade of proteins involved in immune response) seeming to play a significant role. It’s known that inflammatory states generally increase risk of clotting (eg cancer, surgery) but it remains to be seen if COVID is having a similar effect, or a more direct influence.
