Can oxidation marks at routing switch cause the whole system to crash?

My Nexus 5X device got stuck in a infinite bootloop. Because I was still in my warranty period I sent it for repair. However, after the repair shop had been vague about it. They told me the damage could not be covered by warranty because of signs of waterdamage. I was not too sure about their reasoning, mostly because LG devices are well known for having faulty mainboards. I requested the pictures that were taken during the repair and discovered that there were limited oxidation signs visible and only at the routing switch, more specifically the: RF Micro Devices RF1149A Routing Switch.

So my question is: Can oxidation at this chip cause the whole system to get stuck in a bootloop?
