Standard Switches do not support / use LACP.
The only "aggregation" you can use with standard vSwitch is Source-Destination IP Hash, which requires Etherchannel, not LACP.
LACP is a dynamic protocol that allows network devices to negotiate link aggregation. Etherchannel is a link aggregation as well however it's STATIC - no negotiation goes on between switches (virtual and physical in our case).
LACP is only supported and will only work with dVS. And even then it's not really plug-and-play, you would have to set up the Link Aggregation Groups on your dvSwitches and configure hosts appropriately.
Just to summarize - with standard switches you won't see any LACP activity. And if you are only using the default "Originating Virtual Port ID" policy, you don't even need Etherchannell configured on your physical switches. It might be beneficial however in case you at some point figure out that for some portgroups you'd like to switch to "Source-Destination IP Hash" teaming policy (this one is supported on Standard vSwitches).
Hope this helps.
