L&P makes way more than $7k a month. That number was shown on December 2019 when he had 900 patrons. He's hiding his income ever since, but he's got way more patrons these days, and he's also got a Subscribestar account which also generates income. He's also getting donations unrelated to Patreon and Subscribestar. If I had to take a guess, I'd say he makes roughly $20k before taxes.
That is plenty to hire a translator/writer or even one of the many companies providing professional translation services. Also enough to hire a cheap artist to create his DOL renders for Patreon, which can also save a bunch of time.
But he won't do any of that. He's been saying it for years, but never has he done anything. Not 4 years ago, not last year, not next year. He's simply fooling his supporters. Been the case for the past 5+ years. Won't change, period.
