I have been quite delinquent in updating this post - sorry (busy doing 'solar & air conditioner stuff')
1. I grounded all three LL-S chassis directly to the grounding bus bar in the 6000XP. Flicker intermittently continues.
2. Grounded all solar panels of the ground arrays directly to ground rod adjacent to the panels and the combiner box. Flicker intermittently continues.
3. Flickering even occurs on INCANDESCENT bulbs, and makes one of my small UPS units 'unhappy', so it is not due to cheap LED bulbs.
4. Initially it seemed like the 'disturbance' occurred primarily only when the batteries reached near 100% charge, but later it seems to be happening randomly, regardless of SOC or significant solar charge activity, time of day, and independent of any active loads in the house (I'm only feeding 10 circuits into the house via Connecticut Electric generator transfer switch so I can easily turn them all off except for the kitchen lights, which are the most easily and frequently noticed display of flickering, and the problem persists.
5. I bought a cheap digital O-scope and recorded the waveform of the 6000XP AC output: (https://photos.app.goo.gl/Ua2JX6eWu5jN9tEw8)
As I've said, the problem occurs not all that often, not every day, or at any specific time of day, and seemingly not relevant to battery SOC or misc loads. The condition can go away on its own (after a seemingly random period of time) or ALWAYS goes away immediately if I power OFF/ON the 6000XP.
Intermittent problems are fun.
Does the waveform video bring any ideas to anyone? Thanks!

Could you post a few pictures of how everything is wired?
