You could adapt Liquid::Drop and whitelist Ruby's sample method.

See https://github.com/Shopify/liquid/blob/master/lib/liquid/drop.rb#L69:

You would need to change:

blacklist -= [:sort, :count, :first, :min, :max, :include?]

to:

blacklist -= [:sort, :count, :first, :min, :max, :include?, :sample]

Next you could just use:

{{ some_liquid_array.sample }}
