when use other frontend tech we can use global error handler handle all ajax requests.

You can control the UI layout of Blazor Errors in the #blazor-error-ui section in your template, e.g:

There’s no global handlers for handling all HTTP Calls, but ServiceStack.Blazor Component API, i.e. that use ApiAsync can be intercepted in BlazorConfig.OnApiErrorAsync, that’s configured in your Program.cs, e.g:

BlazorConfig.Set(new()
{
    //...
    OnApiErrorAsync = (request,apiError) => 
    {
        BlazorConfig.Instance.GetLog()?.LogDebug("\n\nOnApiErrorAsync(): {0}", apiError.Error.GetDetailedError());
        return Task.CompletedTask;
    }
});
