I think that "neotony" is Liliana trying to be clever (while failing, as usual) and use another word than "cub porn/foal porn", which people would immediately understood as the furry equivalent of lolis. She's trying to appeal to the people against that kind of content, but also posture as smarter than them because seeeeeee, I know smart words! How could I be a pedophile or groomer if I'm against that content AND ALSO know smart words, huuuuuh?!
I think she's specifically talking about the 'actually 1000 years old' trope, where a characer that looks like they're 12 is actually a 1000-year-old dragon or something and therefore legal, but it implies that the people who think that's hot actually want to fuck kids but say it's okay because reasons.
'They don't trust the process'. I highly doubt that the game wasn't programmed to anticipate people doing exactly this, given how robust its decision trees are and how it accounts for all kinds of intensely unlikely scenarios and keeping your options open is a pretty obvious thing for a player to do, so I don't think this is a case of getting snitty that the game doesn't 'learn' your behaviors and reward you for being a two-timing backstabbing bitch.
Real people, in the real world, really don't like that kind of two-timing backstabbing bitchery. The people in-universe would obviously not be best pleased with their leader constantly playing both sides and then deciding at the last second which group to backstab. That doesn't endear trust. The fact that Kreia would be proud is not a selling point.
So first off, if you're doing this, you should be ranking these companions relative to each other, within the context of the work they're in. There are definitely cases where a direct compare/contrast is called for, in the event the two stories are directly linked or the series has specific expectations that it's always been sold on, but in this case the distance in development time and storyline means BG3 should stand on its own, within its own context.
Second, no, you are... holy shit how are you this behind the times?
First the point about 'superior graphics', now about 'epic storylines'. No, people do NOT demand 'epic storylines', that was more common in the late 2000s/2010s. People these days WANT more intimate stories and more inter-character development so those world-ending epic stakes resonate more emotionally. This is why people gravitate toward Persona-- it's not because you're fighting god at the end (that's SMT), but because of the characters dynamics and social links, which are almost universally intimate, small-scale stories about, like... helping out the shy girl in music club, or talking to an old lady by the river during her final days, or helping Kanji come to terms with the fact that he can be a man while still enjoying knitting.
A fantasy story is usually going to have more 'epic' conflicts by default, but they can still tell deeply personal character stories without necessarily breaking the immersion of the world-ending threat. It still has to be sensible within context -- you shouldn't be putting a pause on saving the world because your fully grown adult traveling companion is still upset that their mother burned their velveteen rabbit when they were six and now they need a therapy session thirty years later -- but yes, actually. You are not special and unique for loving 'character driven stories'. This is absolutely a normal thing that people enjoy.
