AI solves exactly the meta-problem you describe: "I had a problem and needed to write a one-off doo-dad utility program to solve it." Now you can do something with your time besides writing pointless one-off doo-dads.
As for monetizing the training data, (a) it cost hundreds of millions of dollars to generate the weights, so why begrudge the companies that made the investment and did the research necessary to make it happen?; and (b) rest assured, whatever your doo-dad does, an open-weight model like GLM 5.2 can generate it for free using your own hardware.
So you don't have to pay anyone in that case. Well, except nVidia, I guess. Point granted there.
