Germany did have long-range Atlantic reconnaissance

Was finding a Torch convoy pure luck because Germany lacked long-range air reconnaissance?

No. Germany had limited but real long-range reconnaissance, including Fw 200 Condors searching the Atlantic.

Finding a Torch convoy still involved luck, but Germany did not lack long-range air reconnaissance. The available force was limited, yet large Focke-Wulf Fw 200 Condors and other aircraft did search the Atlantic. Torch therefore exposed poor synthesis of imperfect reconnaissance rather than a complete absence of sensors.
