I think a lot of their existence for the past 6000 years was to stay out of human affairs unless there was something Gem/corrupted Gem related. That, and they still seem to think of humans as "simple creatures", so I don't think it would even occur to them to ask for help.
Since Jasper is M.I.A. and there hasn't been a lot of corrupted action, I don't think it's occurred to Peridot that she should weaponize herself. I think she and Lapis are mostly high on choosing what they can do with themselves. This will probably change if the Crystal Gems tell them about that just happened with Homeworld.
