If the sub was trailing and detected the array being deployed maybe. Not sure how much flow noise the array would make.
For your second question there was a well known incident where a Soviet Victor III the K-324 ran afoul of the Towed Array of a US Spruance class destroyer during a ASW exercise. The TA rapped around the Victor's screw and disabled her, she had to surface and send someone out with an axe to cut it off. She was towed to Cuba for repairs
In 2009 a PLAN sub bumped the Towed Array of the USS John S. McCain.
