Spilled on MacBook, opened up and now have questions

I opened up my MacBook (model A1706) to check for any corrosion and thoroughly dry it up. After opening I do not see any corrosion on the bottom side. Before I go through and take out the logic board, I noticed a couple things.

First, I’m seeing a few pads with no chips on the bottom side of the board. For example, if you have hinge side facing you, towards hinge side in the middle I see a 6983H smd that has a “220” on it. To the left there’s an empty pad that has solder but no chip. I found a pic of an A1706 logic board but when I zoom in the pic is so blurry. It looks like there’s no chip there but hard to tell. Please let me know if I’m missing a chip and if that’s the cause of my MacBook not powering on.

Second, the batteries are definitely swollen. The second I took the screws off the back, the back plate kinda bulged out from the pressure of the battery bulges. I’m wondering if the battery being damaged could be causing it not to turn on, is that a thing?

If neither of those is the culprit, should I continue my quest of taking the logic board out and trying to wipe it all down with isopropyl alcohol?

Thanks for any help
