lagg and bridge can work together.
I am running machine with FreeBSD 11.2 with 2 Intel NICs: em0 and em1 
combined in to lagg0

lagg0 has 4 static IP addresses

There is also bhyve VM on tap20, this VM has another 2 static IP addresses

tap20 and lagg0 are members of the bridge. This bridge is renamed to 

vm-public: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 
mtu 1500
         ether da:ae:ba:75:53:ce
         nd6 options=1<PERFORMNUD>
         groups: bridge vm-switch viid-4c918_at_
         id 00:00:00:00:00:00 priority 32768 hellotime 2 fwddelay 15
         maxage 20 holdcnt 6 proto rstp maxaddr 2000 timeout 1200
         root id 00:00:00:00:00:00 priority 32768 ifcost 0 port 0
         member: tap20 flags=143<LEARNING,DISCOVER,AUTOEDGE,AUTOPTP>
                 ifmaxaddr 0 port 5 priority 128 path cost 2000000
         member: lagg0 flags=143<LEARNING,DISCOVER,AUTOEDGE,AUTOPTP>
                 ifmaxaddr 0 port 4 priority 128 path cost 2000000

Everything works without any problem.

The only problem in the beginning was PF rules. I added rule to allow 
traffic to the VM IP addresses.
