What role does the oil filter have in all this? Are these shavings/particles simply too small to be stopped by the filter?

Sometimes yes. The rest of the engine seems to be fairly clean, the turbo is going to have some oil in it as it takes it’s oil supply pre-filter.
The crankshaft is fed from oil passaages in the crank so when a bearing fails it usually takes that trashed material and follows the passages.
