I've never seen kits that are precut. They just give you the yardage and you need to cut it yourself. Are you referring to the recent connecting threads catalogs with the flannel kits? Those are definitely not precut, they contain the needed yardage and usually a generous amount in case you cut something wrong. The only precuts I have seen in a kit are laser cut applique units, like in some of the Edita Sitar kits. Those are the only items in a kit I have ever seen precut. All the rest of the fabric is yardage and you are expected to cut it down to the units needed for piecing yourself.
