Not the person who posted it, but I can think of a few ideas for how this would suit tame wise.
Ultimately she would be a utility tame, and possibly a bodyguard style. Non breedable, or breedable with difficulty, especially as Titanomyrma are not tameable.
If it is a bodyguard style, then I could see it being a case of using her pheromones to cause wild Titanomyrma to guard you for a time, and cause them to ignore you otherwise.
As for utility, being a general passive collector is not a terrible idea either. Though I would say it could be a static defense type, though, as an anthill placed in the right place to fight off interlopers could be fun. Most likely mid to late via taming methods, but having utility more as a tribe tame, to protect your fledgeling tribemates and protect your gates from those who mean harm.
Conceptually anyways, hard to say how Wildcard would take to it, but could be fun to imagine anyways.
