This problem should be a recall. My 2006 corvette oil pump had shavings from flat lifters {Exact same problem as yours}. GM lobbied and paid off the right people not to do a recall on faulty lifters/design which should have been done to address this problem.
I got hi vol oil pump w nascar tube zo6 lifters & use castrol {porsche oil} instead of mobile 1. They paid GM for putting their logo on LS2 oil caps.

We commonly rebuild with better oil pumps like in the LSA and also use LS7 genuine lifters and then rarely ever see a problem with lifters

My ve ss series 2 is an automatic I have had it from new always serviced at 10k never flogged it yesterday occasional flat floor,I have had a few mechanics look at it no noise sounds good,its got 220,000kms should I be worried or are the series 2 l77 engines different? And should I wait and fix it when it starts to become noisey and am I wasting my money at this point and electronically disabling the AFM

fix it when it starts to get noisy. But really at 220000 its cylinder sleeves will be worn and it will soon need a rebuild. Maybe wait until then. We rebuild with a cam upgrade from $11350 inc new pistons and a dyno run-in and dyno tune
- changing out the afm lifters wont help it at all
