Update: As I go into battle Erika, I now have 3 new pokemon on my team, a level 21 Voltorb named Aimee, a level 22 Growlithe named Cooper, and a level 19 Dratini named Tyler. Of course I still have Jojo, now level 32, and Phil, now 35. Yes, the 3 new pokemon are very under-leveled. I started the fight against Victreebell with Cooper, getting one ember out before Erika used Acid. I then switched to Phil, who destroyed it with flamethrower. next was Tangela, which I sent Cooper back out for, only to accidentally use bite and got poison-powdered. I used ember and burned Tangela, while it used ingrain. I thought one more ember would do the trick, but then she used a hyper potion. So again I used ember, but before I did she used a full heal in vain, as her Tangela fainted anyways. Then last, but certainly not least, she sent out her Vileplume, i kept Cooper out so he could gain XP, but because of the poison from Tangela, and acid from Victreebell, Cooper was in no way ready to fight. So i switched back to Phil and took an Acid to the face. On Phil's first turn, I wiped Vileplume out of commission. the only change from this battle was Cooper hitting level 23. I'm now debating if i want to go face Sabrina or Koga, but either way I should take care of Team Rocket, and go get my bike.
