It is working better now and I can see the BLE device in the Settings UI.

For reference I had to add the following insmod commands to my init file
to get all the backports drivers to load.

# Bluez bluetooth and backports modules
    insmod /system/vendor/modules/compat.ko
    insmod /system/vendor/modules/bluetooth.ko
    insmod /system/vendor/modules/btusb.ko
    insmod /system/vendor/modules/rfcomm.ko
    insmod /system/vendor/modules/bnep.ko


And I had to double check that Crypto configs were set (which is
referenced in the aosp-bluez docs on the website):

CONFIG_CRYPTO_CMAC=y
CONFIG_CRYPTO_USER_API=y
CONFIG_CRYPTO_USER_API_HASH=y
CONFIG_CRYPTO_USER_API_SKCIPHER=y
