The Rajiv Gandhi School of Intellectual Property Law is the first of its kind to impart law knowledge with an IIT. According to one article published in The Hindu in 2011 ( https://www.google.co.in/amp/s/www.thehindu.com/todays-paper/tp-national/tp-newdelhi/IIT-Kharagpur-adopts-LSAT-for-law-course/article15444678.ece/amp/ ) it does accept LSAT. But still prefer giving their own entrance exam as it's easy and there will be more chance of you getting in. Also the placement record is also damn good tgere.
