Man, that's... It's complicated. Yeah, I know, this reeks of "that 8 year old is really 1000 years old" but...
For those outside looking in, In the manga the kid (literally named Shouta -- aka, "Young Boy") is a young wizard out to prove himself. He tries to summon a demon to show off to his father and Lucoa was bored at the time so she responded instead, partially so no actual demons would respond.

The thing is, she's based on Quetzalcoatl, a male Aztec fertility/agriculture/creator/wisdom god, whose big claim to fame was getting drunk and banging either his sister or his head priestess, and then burning himself alive out of shame. So... yeah.
There's a big "tomboy who doesn't realize she's a babe" vibe (she speaks like a guy in Japanese apparently) going on with the character. And while she thinks Shouta is cute, most of what she does can be explained away by her just being completely oblivious to the fact that she's a gorgeous and well endowed woman. Her being oblivious is a running theme. She's basically a fanservice anime character in a non-fanservice show.
Now, is she a pedophile? Eeeh? The author definitely has a fetish for short if not comically tiny men and large busty amazonian women -- one of his serieses is named ChiChiChiChi (lit: "Titstitstitstits.") about a short guy and his tall and large breasted roommate, and his pixiv definitely has some similar porn on it. He definitely enjoys his titjobs, nursing, et cetera.
Without diving back into the manga because I'd binge it, the general vibe I remember from her was obliviousness crossed with her just being WAY too much for Shouta to handle. He has a similar reaction to seeing Emma's hips during one episode, and other characters have similar reactions when she jiggles - he just can't handle fanservice. At the same time, again, she's completely oblivious. A running gag, for example, is her arriving in locations in extremely inappropriate dress, like a microbikini at a public pool, and having authorities show up and drag her away while she remains confused.
I got less a "no one wants to confront her about her being a pedo" and more a "no one wants to confront her about being a fanservice character" vibe.
To that end, having her be changed from "absurdly endowed tomboy who doesn't really understand how people see her" to "straw feminist who is pissed that the patriarchy is making her hide her navel" is... just kinda dumb, to the point of it being near offensive. Especially since ignoring how awkward all the above sounds, it's probably one of the best manga I've read in years.
The ultimate irony being that Kobayashi's Dragon Maid is... kind of a progressive as hell series. It's basically an urban fantasy series about a lesbian couple raising an adopted young lesbian, while their two male friends are in a heterosexual life partners situation and their other female friend is a sex positive single mother type. SJWs should be falling over themselves to make it as faithful as possible. But they couldn't help themselves and had to "fix" it.
Nah. Well, maybe his old one? His current one is over here:
I looked and couldn't find it.
