Also, are you planning to use Optimizely with Webpack on a Single Page Application? You can find out more on how to set up Single Page Applications with Optimizely using this Knowledge Base article.
"Jquery is bundled into vendor chunk, and i don't want to use "Include trimmed jQuery (1.11.3)"
Could you please expand a little bit?
If you use your own version of jQuery and place it above the Optimizely snippet, then you don't have to include a trimmed version of jQuery.
