Did you find an appropriate poller to use for your 3850s? I'm actually running into the same thing. I don't believe it is reporting on the lsmpi_lo value though. It is reporting on the output of the following command:
show platform software status control-processor brief
If you take the Used sum / Total sum, you will get the percentage that Solarwinds is reporting. Currently my Active/Standby switches run at about 84% and my Member switches run at about 51%. What this leads to is the switch stacks that have more switches show considerably less memory usage than 1 or 2 switch stacks, since the more Member switches in the stack bring down the average. I'm looking to get something that shows a more consistent memory percentage across the switches stacks that have varying amounts of switches in them.
Brendan, the tldr version is that no, we have not found the right poller. Our switch stack only has three switches in it currently, so it's not maxed out. Has anyone else found something?
I ran into the same issue myself on a WS-C3850-12XS-E, and followed the recommendations at this link:
I selected and checked each supported poller until I found one that reported the right results.
Hope this helps.

I ran into this issue on a pair of Cisco 4451 Gen 3 ISR routers. Same issue with lsmpi_io. I followed the directions under A Node Shows Incorrect CPU & Memory Utilization - SolarWinds Worldwide, LLC. Help and Support
In my specific case, I changed the N.Memory.SNMP.CiscoGen4 memory poller to the N.Memory.SNMP.CiscoGen3 poller and they're now showing correct usage values.
