These trainers are not necessarily bounded by their vanilla pokemon. Instead, competitive teams are created using a custom battle generator. The matches get more difficult with time, starting off with low variance but starting to use competitive moves by Gym 3 and items by Gym 4. The gym themes are setup at about 3:1 ratio but may include unknown types. There is always at least 1 from the “may include” column.

Regular Trainers
All regular trainers use the vanilla engine to generate a random pokemon of similar power and type, baring a few special cases to enable uncommon or non-existent types (fairy, dark). Hence, whenever you are in a battle, you can expect the trainer to use the same types they were using before. If they have a dual-type, one is chosen randomly. They start to scale to your level and use competitive movesets later on.
