I found what you are looking for. If you go to mlb.com and click on stats. Then on the left column toward the bottom click on historical team stats. from there you want to look on the left where it says "splits". It will automatically say entire season, but if you open that drop down box you will be able to open the vs Left or vs Right option. This will display the statistics for the teams when they play against a LH or RH pitcher. However, depending what you need these statistics for, I am assuming you are using them for a rating system like me, I do believe these statistics are against all LH or all RH pitchers that pitched not just the starters. But, this may be good because they are complete statistics. Hope this is what you are looking for.
If you are doing a rating system I'd like hear about your strategy, I can share mine with you as well
