You may be able to do that just in Liquid, but it could less of generic solution like the one provided by @Brendan. According to this article, you can generate a random liquid number between min & max. So simply:

• Assign the min to 0 and max to your array's length.
• Loop over the array till you find your random number and pick you element.

Here is an example, get your random array index:

{% assign min = 0 %}
{% assign max = prefix.size %}
{% assign diff = max | minus: min %}
{% assign randomNumber = "now" | date: "%N" | modulo: diff | plus: min %}

Then find your random value:

{{ prefix[randomNumber] }}
