Same here, they were seen as less effective that the AMX-13, and the IDF wasn't real fond of those. No one particular faction in Lebanon had enough of the M-41s to make a difference, and I don't think Jordan deployed any against the Isrealis, only Cents, M-47s and M-48s.
It's very difficult to effectively utilize captured vehicles unless the quantity captured in good condition makes it viable (T-55/Tiran being a notable exception), both from a spare parts viewpoint, and friend/foe recognition issues, both experienced by the Germans with captured Russian vehicles. In fact, one of the main reasons the IDF added the turret stowage bins to the Tiran was as a recognition aid.
