That's true, and it's intended behavior. The idea is to distinguish between language and regional formats, and the latter variables are considered to be part of the language option.

Yes it is. If you want the same locale for every locale category, just make sure that you select the same locale for both language and regional formats.

LC_ALL is typically used by coders. It's not suitable as an environment variable on a desktop, since it makes any UI for this purpose useless.

If you want to make an exception for a particular locale category, e.g. LC_CTYPE or LC_TIME, then set that category separately. But leave LC_ALL unset.

It doesn't. PAM loads ~/.pam_environment at login.
