The text book approach is group-adjacent:

<xsl:template match="*[listBulleted]">
    <xsl:copy>
        <xsl:for-each-group select="*" group-adjacent=". instance of element(listBulleted)">
            <xsl:choose>
                <xsl:when test="current-grouping-key()">
                    <xsl:copy>
                        <xsl:apply-templates select="current-group()/node()"/>
                    </xsl:copy>
                </xsl:when>
                <xsl:otherwise>
                    <xsl:apply-templates select="current-group()"/>
                </xsl:otherwise>
            </xsl:choose>
        </xsl:for-each-group>
    </xsl:copy>
</xsl:template>

It doesn't match on listBulleted, however, as that is not the container where you need to group.
