Thanks Timothy! I suspected so, but wanted verification. I don't know
why z/OS Comm Server can't support LACP but the OSA cards can (and
z/VM). I'm not a networking guy though.

No, I don't think so.
Anticipating the next question, you can often configure network switches to
handle LACP on z/OS's behalf. This IBM technical article illustrates one such
scenario:
https://www.ibm.com/support/pages/increasing-available-network-bandwidth-leveraging-link-aggregation-and-multipath-routing
This article specifically concerns the IBM Db2 Analytics Accelerator when it's
running on a separate physical machine. However, the same basic approach should
work for other applications.
When z/OS runs as a z/VM guest it should benefit from z/VM's support for link
aggregation, so that's another possible option.
