Does coding with LLMs mean more microservices?

I don't see a direct causal link here - architecture choices are still mostly about suitability and the specific needs of your app. That said, if you do opt for microservices, modern Edge runtimes like Cloudflare Workers and lightweight frameworks like Hono have changed the game. They’ve made deploying and maintaining microservices significantly easier and more cost-effective, while providing incredible performance.

I have built both monoliths and microservices over thirty-plus years, and the honest answer is that LLMs make it easier to generate more code, not better architecture. The hard part of microservices was never writing the services. It was debugging the network calls between them at 3am when one service silently started returning empty responses. LLMs do not help with that. They just help you create more services to debug.
