As far as I understand, libasound_module_pcm_pulse.so is the ALSA
plugin that re-injects the sound output into PulseAudio. It allows
application written on top of ALSA to work nicely with PulseAudio. We
don't have a package for PulseAudio at the moment, but for your
project, you probably don't need it. You should tell your Flite
application to directly talk to ALSA devices, and not configure those
ALSA devices to loop back into PulseAudio.
