Charmander if you can smother it's tail.
Maybe Metapod if you could pry of bits. I assume they work similar to real life cocooning bugs and liquefy themselves.
Poliwag, grab it's tail and slam it against the ground.
Togepi, kill it before it can metronome and you're good.
Hoppip, rip off it's top leafs and it probably can't move around and will be easy to take out unless if gets a spore off on you.
Sunkern, no explanation needed.
SIlcoon/Cascoon, same logic as metapod but a squishier shell.
Slakoth, no mobility, probably wouldn't be able to stop you once you got a hold of it's neck.
Azurill, really only has it's tail to strike back with.
Luvdisc, take it out of the water and hold it down.
Budew, split it in half easily.
Lillipup, strangulation
Litwick, Snuff it out
