The spelling of "one and alls" is not correct. The word "all" is already plural, so adding an "s" to the end is redundant. One possible explanation for the error might be confusion with the phrase "one and all," which means "everybody." The correct spelling is simply "one and all." In IPA phonetic transcription, it is pronounced as /wʌn ənd ɔːl/. Remember, it's always important to double-check your spelling to avoid mistakes like this.
