There's https://labs.google.com/pomelli/about/ which is pretty much exactly what you describe. It does do prompt in, image out but also accepts your brand from a URL, and then allows for remixing and tweaking after the fact.
It's not all the way there as far as I can tell, as it'd be great to upload a proper set of brand guidelines and tone of voice, and maybe some user personas. Also the inpainting in the additional steps seems limited. And the output is limited to certain dimensions it seems.
Other tools exist within suites like Jasper.ai for marketers.
After that there may be some 'roll your own' options via N8N or other Ai workflow tools, letting you plug services in, tweak system prompts and add manual checking and tweaking/approvals via Slack/Teams etc. I've seen full automated/human-checked workflows for blogs, image editing shouldn't be dissimilar.
