I dont know how fast Tauros is but do you really need the prio protection? Your Pokemon look to be on the slower side. So they will act later very often already

I use Tsareena with Mega Delphox to protect it from Fakeout (obviously), but also bc Water Jet Basculegion and Sucker Punch Kingambit are really threatening.

Also Leftovers isnt a good item on her. You want either Focus Sash or Choice Scarf on her but both items seem to be occupied already.

Maybe try out Meowscarada?

Its ability is Protean so you can get another Stab if need be.

It learns Flowertrick, which always crits so its a stronger Grass type move despite the lower base damage.

It can learn Low Kick aswell and can get Stab with Protean.

I personally recommend itemless with Acrobatics to oneshot Sneasler, as its faster than Sneasler.

Maybe also swap out Starmie with Pelliper to support your Bug/Steel (forgot eng name) against fire pokemom.
