I feel like Grom may as well not exist in this fight, it's like asking if Hawkeye could stand a chance against Thor and Captain Marvel.
Lei Shen is a bit weird due to the fact that a lot of his power came from siphoning Ra'Den and seemed to require the use of the Throne of Thunder itself to control. I feel like if the fight took place in the Throne of Thunder, Lei Shen would come out victorious as his potential would surpass the Lich King in that situation, but in any other scenario it would likely go to the Lich King.
I know some blizz dev questionably said that Lei Shen would beat the Lich King, but you have to consider the above. Lei Shen's power is kind of location based, you cannot rely on that in an arena styled melee fight.
