Looking at your roster, your off-meta (non-GL) Jedi aren’t strong enough to take on an optimized SLKR team.
The team comp you’re looking for is:
JKR, Bastilla, HY, JKL, Old Ben
It isn’t an easy counter. You need them modded in a specific way, need to meet certain speed thresholds, and need a specific strategy. Even if you do everything “right,” it’s still far from a guaranteed victory. You’ll likely need them all relic’d, with JKL at a minimum of r7.
I suggest doing a search on YouTube, writing all the specifics here is daunting. I highly recommend “Xaereth Prevails,” I believe he was a pioneer for this off-meta counter and breaks things down very well. Plus, you can watch him successfully do this counter over and over again to help make sure you get it right.
