hdmi_ignore_cec=1and hdmi_ignore_cec_init=1 both relate to the firmware based display stack only.
CEC is optional within the vc4 driver, so adding an override to disable it should be relatively straightforward - I'll add it to the to-do list.
ARC uses CEC as part of the negotiation, so if there is some upset then it is likely to fail. I am slightly curious as to what is upsetting the LG or Sonos, but CEC is not a trivial one to debug.
