In my personal experience, it's never because they don't chew enough. Healthy birds never have overgrown beaks whether they chew or not. But just because a beak is overgrown, it doesn't mean that there is liver problems (it's always the liver). It could be that the 'bite' is not as aligned as it should be and, because the top part does not 'rub' enough or evenly on the edge of the bottom part, it just keeps on growing (I have a quaker that requires periodic trims of both her beaks because of this). The beak is overgrown but it seems to me that there is a bit of a deformation there (the lower beak seems to be not quite 'placed' exactly right under the top). Taking him to the vet is what you need to do (ask for a bile acids test to make sure it's not the liver) but, if I were you, I would not use somebody who is not experienced in birds to trim anything because the problem could have been caused by a bad trim to begin with (sometimes birds get a large chip on one side of the top beak making the lower beak grow more on that side and, if this is not trimmed correctly, the top will grow unevenly and, in time, will cause the lower beak to shift to one side). Slightly misaligned beaks can also be made to align right with expert trimmings so it never pays to go with somebody who is not an avian vet for these things.
Don't worry about the crack, it's only at the tip. They might not be able to cut the entire split off when they trim it right (that was a real shabby job of a beak trim!) but it will grow out in time. Beaks can be permanently split (I had a couple of birds with this problem) but it means splitting all they way down where the matrix of the beak is and that means bone so it requires huge trauma for this to happen (cockatoo breeders split the beaks of the males on purpose).
I am not 100% sure but I don't think this is a liver problem (but check it just in case because this is very young bird and, if there is something there, you can treat it with diet and supplements). Having said that, I would urge you to re-evaluate his diet because free-feeding protein food (pellets, seeds, nuts, nutriberries, etc) is not recommended for GCCs.
