I think I found the case of the bug and will post a fixed version soon.
As you discovered Letitia simply replaces an existing npc as she is added through the Adepts mod as you concluded. She is one of the recruitable characters who is only available if your hero is of a certain gender. In this case female. I believe that you're probably playing as a male hero in which case she can't be recruited by you. As you can see from bare_elf's post she can be recruited successfully by a female hero after some penny pinching to raise the cash.
If your hero is male, what's suppose to happen is she says something along the lines of that she wishes she could go with you but has to wait for Banek to return. However I forgot to add that conversation to her instance in actor.gas so instead she defaults to the first conversation in her conversation block which is her acceptance speech.
Its a case where the developer of the mod knows what's suppose to happen and tests to that probability but forgets to test other possibilities. Let me know if you find any other bugs. Some that are already listed in the known issues text are beyond my knowledge to fix but other silly little bugs like this one should be easy enough to fix.
Thanks for the quick bug report.
