Review Comment:
I suspect carrying over the camel-case was unintentional.
```suggestion
Aws::Crt::Io::EventLoopGroup event_loop_group(ev_threads);
Aws::Crt::Io::DefaultHostResolver default_host_resolver(
event_loop_group, /*maxHosts=*/8, /*maxTTL=*/30);
auto client_bootstrap =
Aws::MakeShared<Aws::Crt::Io::ClientBootstrap>(
"Aws_Init_Cleanup", event_loop_group, default_host_resolver);
client_bootstrap->EnableBlockingShutdown();
return client_bootstrap;
```
