You forgot the next sentence I say after that line, which says "or at least someone that gives the impression that they're a mommy", basically saying that although they may not be actually a mommy, their initial impressions and design give off mommy vibes.
And we have
Meloco from XSoleil
Scarle from Iluna
Nina
Kaela from Holoid 3
Reine from Holoid 2
Fauna from Holoen2
Kiara from Holoen1 (shes actually motherly in a lot of situations if u pay enough attention)
Lamy from Holojp5
Etc. I think I can confidently say almost all recent corpo generations somehow always has a "mommy". Not all of them, of course, but the abundance is there.
I'm going to make a loli episode just to make u mad
