You forgot the link to [1].

Never used loop-aes myself. Sorry if I miss the reason for your

Opening a dmcrypt volume creates a mapped block device in /dev/mapper.
You treat it like a partition and format it with ext4. Unless you use
some exotic flags for mke2fs, the journal will be put on the same block
device and is encrypted along with the rest of it.
So: No need to worry about it.
