So your boot CPU rail at the main max pmic on the back of the board will normally read anywhere from about 10 to 30 is ohms relative to ground which is normal
Your main CPU rail at the Max IC front side of the board will read pretty much the same. So I think provided none of your other primary rails were short to ground, I don’t think either of the Max ICs are/were your issue.
That being said, there is clear signs of liquid surrounding the missing Max IC in your photo, so it’s probably for the best that you removed that
No worries
