Hi there :-) I think the use of 'bots' is a sort of happy slightly childish and familiar extension to the word 'thrill', and meant to accentuate that word'. The idea is similar, but not quite the same as when someone calls someone 'babykins'. This would only be said between two people who are extremely familiar with each other and is a term of endearment. 'Bots' is similar but it's modifying the word 'thrill'. A bit difficult to describe but I hope it gives you the idea. Regards

Hi HUxy! I understand "bot" as a computer program that does automated tasks. They are also called software robots or software agents. I hope it helps. Rafael

Without seeing more context (I mean, probably watching the whole movie), I guess "bots" is either a nickname, or a strange habit of speaking by that character. It's not common or standard at all.
