None of the listed words rhymes with the whole word 'foolishly' (/ˈfuːlɪʃli/). 'fool' and 'foolish' genuinely share the stressed vowel and the /f/ onset, and 'cool' rhymes with 'fool' (/fuːl/ vs. /kuːl/). Warning: 'childishly', 'selfishly', and 'stylishly' only look similar on paper; their stressed vowels are different (/tʃaɪl-/, /sɛl-/, /staɪl-/), so they do not rhyme with 'foolishly'.
