Texas has tried pretty much every piece of trope certain political parties like to trot out to "fix" medical care, including tort reform. It hasn't done a damn thing.

What percent of, say, Merck's annual budget goes towards paying out due to court cases they have lost where tort reform might make a difference? (I mean, ignore any lawsuits surrounding business practices, or from a competitor) Or pick any other pharma giant.

I tried to google it myself but didn't find anything clear on the matter.

What nonsense. It's out of patent. There's no cost anymore except production and distribution. It's not a matter of recovering costs anymore, it's an oligopoly fixing the prices.
