I can only speak from my own experience, but if you're anywhere close to the limits that Lambda imposes, then you should probably have already converted those functions over to Fargate or your own ECS or EKS clusters a long time ago. Many people abuse Lambda as a way to quickly launch an instance that's supposed to last for a relatively long time instead of one whose lifespan should be measured in terms of milliseconds or maybe just a few seconds.

Lambda gives you way more rope than you need to hang yourself many times over.

Don't get me wrong, it's a great tool when it fits your use case, but there are a lot of people who got started with it without really understanding their serverless use case, and because it worked so well they just never bothered to do their due diligence to find out if it really was the right solution. And even if they did do their due diligence at the time, they just cast that decision in stone and never came back to it.

It is possible to build and run a Tier 1 class service and take dependencies on serverless technologies plus DynamoDB and other Tier 0 or Tier 1 services. More than a few services at AWS are built that way. But you have to be careful when incorporating Lambda into that kind of equation.
