You cannot catch wild Chikoritas in any official Pokemon game.
Unfortunately, you can't catch a Chikorita in the wild. You'll only be able to find it if you choose it as your Starter Pokemon or you chose a Totodile as your Starter (in which your rival will choose the Chikorita). Or you can trade another Pokemon for it in the GTS.
Your only chance to get a chikorita in the game is by choosing it as a starter Pokemon. Chikorita cannot be caught in the wild. It cannot be obtained through in-game trades, either. You must trade to get it from another person (via Wi-Fi or wireless local communications).

You can't catch chikorita so have a friend trade you one.
You can't. You can only get it as a starter.

Chikorita cannot be caught in Pokemon FireRed. However, you can catch a Bayleef in Pokemon Colosseum, transfer it into FireRed, and breed it to get a Chikorita egg.
Answering "Can you just catch 200 Pokemon on your national pokedex to get chikorita cyndaquil or totodile?" Hell no!

Chikorita is a starter pokémon in Silver, Gold, Crystal, Heart Gold and Soul Silver. If the games are compatible you can trade a Chikorita from one of those games to your own. I don't believe you can get a Chikorita in the wild.
Chikorita is a starter Pokemon in soul silver and heart gold you can't find it in the wild, but if you just want to battle it some trainer may have it.
You need to catch every pokemon in Hoenn and then go see Professor Birch and he will let you have either totodile, chikorita, or cyndiquill.
