Two cmdlets that do not work properly when this is happening are Install-VMHostPatch & Copy-DatastoreItem. A good indication of the proxy being involved is exceptions that have items like:
Proxy Authentication Required

To work around this wrap the code in a Set-PowerCLIConfiguration proxy avoidance.

$CurrentProxyCfg = Get-PowerCLIConfiguration
Set-PowerCLIConfiguration -ProxyPolicy NoProxy
...
Install-VMHostPatch [...]
...
Set-PowerCLIConfiguration -ProxyPolicy $CurrentProxyCfg.ProxyPolicy

Thanks to @cshanklin & @lucd for their assistance in aiming me down the right path.
