Nothing's wrong with it, it's just loli.
Akira Toriyama was a lolicon. All the greats in animation and cartooning are lolicons, even in the west. Hayao Miyzaki is a lolicon. Walt Disney and Max Fleischer were lolicons. Your favorite mangaka is a lolicon. That series you like has loli in it, or its creator worked on a loli series, or they have a filthy pixiv full of lolis. The guy who made the character designs for that Megaman game you like is an unrepentant lolicon. That vtuber you watch is a lolicon. The animators who worked on that series you liked were lolicons.
I won't bother guessing at the mechanics behind it, but for whatever reason, creatives in this sphere tend to be lolicons, even if not exclusively.
As for Toriyama in-particular, I think that the prevalence of muscularity in Dragon Ball Z leads people to forget that he LOVES drawing lolis. It's just that DBZ in particular has such a global audience and took off on such a scale that stuff like Arale-chan or even Toriyama's designs for stuff like Dragin Quest and Chrono Trigger get overshadowed. That's how you get Gogeta memes attacking lolicons.
Did you like Dragon Quest XI? Veronica. Hugely popular loli. Highly attractive (don't you fucking lie to me). Tons of hits on any site that hosts loli fanart. Toriyama's design.
Which brings me, incidentally, to the weird fixation he has on de-aging characters back into kids.
