(Basically everything except Jolteons, Flareon and ninetales. You might be able to do the latter 2 with a team of level 30 kyogre.)

You could definitely do Flareon and Ninetales with L30 Kyogres, and you could come extremely close to doing Jolteon with L30 MS/EQ Groudons (might be able to do it with luck if you tried enough times).

You could probably do azumarill and piloswine, but you will have to get more specific, What do you have etc.

You could read the Solo Guide. It recommends a minimum trainer level and minimum Pokemon level for the best counters. For non-idea counters, you'll have to use your brain a bit and cross reference the counter chart to know if they are viable and what level you will need. Happy hunting!

Basically everything can be soloed with the weather boost.
