Yes and no.
Komi-san indeed have a dialogue there but it's not the actual scripted word, she spoke her own true feeling.
Obliviously the audience didn't know or notice it, only their own cast/class members know the actual script, this is why the narator seem confused.
Of course Manbagi knows it too, it's not self improvisation but an actual confession of Komi-san.
I'm not sure if Manbagi ship is sunk yet but I'm pretty sure it got hit by Komi torpedo.
