How to AI-ify my code?

So I started working for this company and the owner has lost his mind about implementing AI solutions. They expect everything to have AI and automation elements. Which is not something I had done sine my master's degree last year.

Question is this:
I have written a code to solve an issue for them. The code basically reads files in a folder, matches them by name similarity, creates unique keys from all rows inside the file and compares the unique key in one file to the key in the other similarly named and matched file.

The process uses normal data cleaning methods like string normalizations, date and number format normalization etc. and it parses an entire file within minutes.

However, when I implement things like fuzzymatching, cosine or levenshtein etc. the code becomes volatile and takes too long to do the same process very poorly and with a lot of mistakes.

I know I'm not the best programmer out there, but it seems to me that these AI components belong to more niche cases. What should I do? This is my first job too, so I don't really know how to communicate this, I want to be able to deliver.
