Yes, you are eligible for a transit without visa, as you are going to the USA and will be having a valid US visa.

However, I don't think you have booked the flight in single ticket. KLIA2 is only for low cost carriers like Air asia. AFAIK, Air asia doesn't connect to carries which departs to USA in KLIA. If you have booked seperate tickets, you will miss the second flight if first flight is delayed.
Just tips to get there fast.
Happy journey. In my opinion, 3:30 is a very short time to do this. I wouldn't count on it. Change the ticket to an earlier time if you can.
Update: I am not sure whether transit visa is available for people not using Malaysian airlines or Air Asia. I suggest to take a E-Visa online (NOT E-NTRI), to avoid any confusion or problems, especially since you don't have much time.
