I don't think they'd give a trainer Ditto and obviously not for the Legendaries. I know they gave a scientist in GSC a Ditto but there are usually problems that come up when using Ditto. Also I'm just playing the levels off by ear, I don't remember the specific levels of the Routes so adjust with accordance to other trainers.
