Report to audit virtual servers without ASM policy or ASM policy disabled
We are looking to report on two issues: 1) All virtual servers that have no ASM policy applied, and 2) All virtual servers that have LTM policy rules that disable ASM policy
For 1, I know I can run the tmsh command, list ltm virtual policies, and eyeball the output for any that have "none", and I know for 2, I can run list ltm policy rules and search for asm disable rules, but those are clunky manual methods and not practical for ASMs with a lot of VS's. If we could at least narrow down the output to only list what we need, that would be helpful, but I couldn't figure out a grep filter to do it myself.

You can obtain a list of all virtual servers that have no policy (and hence have no traffic going via ASM) via this command:
tmsh list ltm virtual one-line | grep -v policies | cut -d' ' -f 3

Syntax error: "cut", grep is currently the only filter that is supported.
Guess I should have stated we are still on 11.5.x.
However, even without the cut pipe we still get which VS's don't have policies so thanks. I can then combine that with a search on all ltm policies with no ASM policy enabled rule: list ltm policy one-line | grep -v "asm enable" -e sys
As far as my second question, I can search on all ltm policies with an ASM policy disabled rule: list ltm policy one-line | grep "asm disable"

The script I provided was meant to be run from the linux shell, because of the flexibility of having access to linux utilites like cut (and sort and uniq, for example).
Here's a one liner that prints out virtual server and policy names when the policy includes 'asm disable':
for policy in `tmsh list ltm policy one-line | grep 'asm disable' | cut -d' ' -f3 `; do echo -n `tmsh list ltm virtual one-line | grep $policy | cut -d' ' -f3`; echo ::$policy; done

Another long term solution is BigIQReport - https://devcentral.f5.com/s/articles/bigip-report
The latest version provides both way to to search and report of VIPs with no ASM policy as well as a way to see traffic policies attached. In our case we disabled ASM via iRule for WebSocket support that was lacking in ASM on version 12.x. We run a Windows task which runs every night to gather fresh captures of our configuration. BigIQ is another, but that is a bigger task. You can setup BigIPReport in a hour or less.
