These three pieces are not attached and I was wondering if A: they’re the reason the Mac is nearly unusable as it has super high kernel task, and B: if it’s possible to reattach them

Caner Saka just for completion sake. If the parts that are loose are indeed from the area you marked then those are as follows. U5860 is a TMP461 QFN temp sensor C9340 is a 22µF 10V 20% capacitor in a 0603 package C9344 is a 22µF 10V 20% capacitor in a 0603 package U5860 belongs to the Airflow Right circuitry and the capacitors are part of the Piccolo secondary PMIC circuit. These are relatively straight forward resoldered by anybody with some experience with a hot air rework station.
I would consider sending this one in to a board level repair shop. You can get quotes first. PowerBook Medic will be cheaper https://www.powerbookmedic.com/repair-ce… or The Rossmann Group https://www.rossmanngroup.com/about-us/w…
