I think the A is for asexual.. like why tf would someone not interested in sexuality care. At a certain point it's just someone wanting attention and I think we passed it a few characters ago. Before you, gentle reader, get upset see it for yourself.. these come from Google search, obvious joke ones were ignored:
LGBT
LGBTQ
LGBTQ+ <- this is literally all inclusive, no need to go further
LGBTQ2 ("two spirit".. aka furries)
LGBTQIA+ (longest "official" acronym)
LGBTQIA2S+
LGBTQIAAP+
LGBTQIAGNC
LGBTQQIP2SAA
LGBTIQCAPGNGFNBA+
If that doesn't make it obvious I'll leave you with a quote from Peter Tatchell:
It’s great to be inclusive, but the new alphabet soup is a confusing and alienating mess — made even worse when people get into spats over missing initials or the inclusion of initials they disagree with. The longest I’ve ever seen is LGBTIQCAPGNGFNBA. This is absurd. It makes us a laughing stock and devalues serious issues around sexuality and gender.
