You have to enter the encryption passphrase. It makes little sense to do
all this otherwise.

First one definitely won't do it, so it's the "installer environment".

This. My suggestion is to use bind-mount before chrooting there.

mount --bind <source_dir_with_packages> \
	/target/<target_dir_where_packages_should_be>
