How much tummy time should I be giving my 11 weeks old LO? Should it be on a daily basis? and Split into multiple session?

Once your LO wake up and being active, you can turn over and let your LO train his neck strength, once they tired they will cry or lay down on the bed or playmat. I never count how many time he must do or he need to do. Oh ya, can help support them higher with a pillow on top of their chest or bolster also can. Baby pillow bolster work fine.
