if these things were in botw it would probably be easy. i have a lot of good weapons in botw., and urbosa's fury. I have also beat Maz Koshia a few times, so if they were in botw, i would have beat the by now
I wouldn't call them that much of a threat. Worst case scenario you use riju to kill them. You should have a steady supply of electric materials and you don't see them much except for when you fight them while trying to chase Zelda in Hyrule castle or when completing the dungeon
When you're at the beginning of the game and you finally land in Hyrule everything will be scary because there is a good chance that you will get one-shotted by a random enemy unless you cook a dish that increases your defense or quickly try to speedrun shrines.
