flatMap -> mapで配列を2回転している & 内容でisValidElementのチェックが2重でかかっている & Fragmentが複数ネストしている場合に対応できていないので以下の感じはどうっすかね?
(動作確認自体は未対応ですが...)
const childrenToItems = (children: ReactNode) => (
Children.toArray(children)
.reduce((prev, child) => {
if (isValidElement(child)) {
if (child.type === Fragment) {
prev = prev.concat(childrenToItems(child.props.children))
}
prev.push(cloneElement(child as ReactElement, {
maxColumns,
termStyleType,
}))
} else {
prev.push(child)
}
return prev
}, [] as ReactElement)
)
...

概要
Deprecatedなitems propsから置き換えようとしたらうまく動作しないケースが有ることに気が付きました。
以下のように条件分岐で
DefinitionListItemを複数セットしたいケースがありますがこの場合にうまく動作しません。変更内容
Fragmentか確認してchildrenを取り出して今までの処理を通すようにしました
備考
以下ならこのままでも動きます
