Yes, 7K miles seems to be the typical OLM interval. I think that is reasonable using good synthetic oil, though I don't begrudge others their more-frequent changes. Checking the level a few times between oil changes, the LF3 does not appear to consume oil through this interval.
The LLT chain issues involved longer programmed OLM intervals so people who didn't ever check their oil would run low with an oil-consuming engine, quality-control of their chain vendor, along with switching to the silent chain type rather than the noisier roller chain.
My 2009 LLT was not (I think) ever run low on oil, and had regular maintenance. It had slight chain symptoms at 130K miles, and a single incident of the P0008 code which never returned in the ensuing 3 months. Replacing all the timing components, including the actuators, fixed hesitation at throttle tip-in, quieted the engine and restored power and fuel economy.
It is important to source quality components for this repair, I used OEM. My understanding is some brand-name timing chain companies are sourcing components from China. Control of the manufacturing and heat-treatment process is critical for these parts to live a long life.
