What do you want me to do? Not make games?
My advice is to ignore the folks who outright hate AI. You'll never satisfy folks who reject everything AI-centric, it's fine. The majority of players won't care if your game is good and has content they like.
Everyone starts somewhere, and I really do think LLM tools lower the barrier for entry to this stuff. You can definitely learn some basics and get the ball rolling, but I'd use it as a supplement more than the main path forward. A quick Google search shows a lot of Ren'py coding tutorials (you might even find resources here on F95Zone also, there's a
programming and development subforum here with lots of good discussions).
Start small! I'm not a big Visual Novel fan myself, but I think VNs like your other game are a great way to start learning since they're often straightforward "Choose Your Own Adventure" stories with a few branching paths and minimal game mechanics. Maybe focus on that one for a while, keep it simple and don't let "feature creep" unravel the project. Try and get a completed game or two under your belt, shorter VNs that take you six months to build can teach you a ton. You'll learn so much if you work at it, you may even get to a point where you no longer need the LLMs for coding assistance. That's the real goal, in my opinion
You got this man. Like I said, I think your image workflow is solid and that's already a step ahead of most AI games that are still using the common and older Stable Diffusion or Pony models. If you can start learning the coding side of things you'll be off to the races.
Lastly, don't be disappointed if you don't strike it rich with this stuff, cause you almost certainly won't. I don't say that to be mean or anything, it's just that porn games are already a small niche and a fickle beast, the vast majority of creators won't earn a living doing this. The ones who are getting decent earnings have been grinding away at it for a long time. If you can stick with it, you might get there too... you also might never make this your full-time gig. That's why I personally think it's important to make games that
you enjoy. If you're having fun while making your game and you're excited for its direction and updates, you'll stick with it a lot longer (and players will pick up on that enjoyment too).
I'm rambling, sorry. But I think anyone can be just about anything they want if they put in the effort, and game development is no different. If you're enjoying the process, and you like what you've made, then keep at it dude. Good luck

EDIT: A small tip that has helped me to understand code in my personal projects (I don't release anything, I have a few little text adventure games I've made just for my own personal enjoyment but they'll never be released) - Use tutorials or online Ren'Py documentation as your primary resources for learning. If you get stumped on something, ask the LLM to explain or help you understand. Treat it like a teacher, not an employee. Don't just ask it to generate code and then copy/paste that into your project because that doesn't really teach you anything (or it didn't for me, anyways) and you can't really even verify if it's accurate.
Instead, ask it to elaborate on
how things work or what various functions or operations do, then take what you've learned and write the code out yourself and implement that into your project instead. It will be very, very slow at first, but the more you learn the faster you'll get at it. Eventually you'll even start to notice the stupid mistakes that LLMs commonly make and the weirdness, and at some point you'll start using it less because it'll increasingly piss you off with its dumb mistakes or random hallucinations, lol
