2GB is enough for LibreELEC.
You only need more if you want to run additional services (e.g. using docker).
There is no fix for what you linked. It is by design. By default power is available for HATs after a shutdown.
If you are not using a HAT that requires that you set POWER_OFF_ON_HALT=1 and get the lower power consumption.
The 2GB is enough for normal LE use. If you want to run additional services in the background (docker, tvheadend, etc.) the 4GB or 8GB variants would be more suitable. The eeprom option POWER_OFF_ON_HALT=1 is not configured in LE by default, but you can change that yourself if desired.
Thank guys, a 2GB it is then.
Can I change the eeprom option from LE itself or do i need to boot into rpi-os or raspbian ?
It is by design
Like buying a car that intentionally leaks gas, just for those that want to pull a trailer. Seems like a design flaw workaround to me.
Thanks for the advice, it really helped me

You can ssh in and run:
rpi-eeprom-config -eLike buying a car that intentionally leaks gas, just for those that want to pull a trailer. Seems like a design flaw workaround to me.
The issue is there exist HATs (not ones designed by RPi...) that can be damaged if 5V is provided (which comes straight from USB power connector) but 3V3 is not (which comes from PMIC which ideally would be powered off on shutdown).
So, yes it is a workaround, but not for a design flaw that the Pi created.

That makes sense, preventative measures do not work after the fact. Nice I learned something today
