Hi @jbailey
You're right, we don't have the LS Helpdesk feature in the cloud. There are no plans to port that same capability over to cloud, but we are committed to continuing our support for it in its current state onprem. However, there are a number of options in our integrations marketplace that can help with that, you can find the list here.
Additionally, you're welcome to join our beta program for Flow Builder, which we announced yesterday in our fall release, where you'll be able to automate ticketing with a number of off-the-shelf products with ease.
Hope that helps
