Missing dictionaries were built from wordlists (using dicttool) which are in LatinIME:
https://github.com/LineageOS/android_packages_inputmethods_LatinIME/blob/lineage-16.0/dictionaries/

Now both have the same amount of 32 languages.

Default dictionaries (de, en, es, fr, it, pt_br, ru) don't need to be added again, are included here:
