Encrypted /boot isn't supported by Fedora's installer. GRUB 2 has
supported this for a while, and it's also possible to setup a keyfile
so all you have to do is give a password once to GRUB and then you
don't get a plymouth passphrase entry UI. The encrypt the PV vs
encrypt the LV are both supported by the installer, but I guess
there's some bug with the latter variety (I didn't completely follow
the bug). The former is done by choosing encryption at the time you
choose the drives to install to, and the later is done in
custom/manual partitioning by clicking on a mount point, and then
modifying the volume on the right side UI, an option in there is to
encrypt.

You might have better luck deleting the LV you don't want anymore,
making a new mount point (and hence a new LV), and encrypting it -
rather than reusing existing.
