Short answer: Avamar clients are not required for backing up VM's. You don't need to install the agent on any VM. The client and proxies do not rely on each other at all, except in a single special case*.
Avamar does not install the client anywhere automatically. Avamar Client is an MSI package you can script for automated deployment.
The client would only be absolutely necessary for backing up physical computers (laptop, workstations, bare metal servers) or if you have not licensed the virtualisation hosts for Avamar.
The client may be necessary if you are backing up databases because the VM snapshot can interfere with the VM operations, and/or the backed up data may not be 100% consistent. With the client + appropriate DB plugin you can also backup/restore straight to/from database without using SQL dumps.
If your VM's are using RDM disks - used with Windows clustering for example - the RDM's couldn't be backed up with proxies anyway, you'd need to use the client.
*There is an Advanced Policy option to orchestrate the VM backups together with SQL backups so that you would always get application-consistent backups.
