The easiest way to beat any boss in KOTOR is to LOS (line of sight) them, hide behind one of the pillar thingies (or any obstacle they cant hit you through) and heal + buff yourself (just make sure that the boss doesnt sneak up on you, lol). I managed to beat Kreya (traya) despite only being level 23 and I just recently started playing again after a 4 years break. Honestly the AI could need some work, it looks really stupid when one of the bosses keeps thinking they can run through a wall to get to you.
