This could work:
\define line-through()
<$action-setfield text="~~$(text-field)$~~"/>
\end
\define uncheckactions()
<$set name="splitregexp" value="[\^~~][~~$]">
<$set name="splittext" value={{{
[[$(text-field)$]search-replace:g:regexp<splitregexp>,[]] }}}>
<$action-setfield text=<<splittext>>/>
</$set>
</$set>
\end
<$list filter="[regexp:text[^TODO |^~~TODO ]]">
<$set name="text-field" value={{!!text}}>
<$checkbox field="text" checked={{{
[<currentTiddler>get[text]prefix[~~]] }}} unchecked={{{
[<currentTiddler>get[text]!prefix[~~]] }}} checkactions=<<line-through>>
uncheckactions=<<uncheckactions>>>
{{!!text}}
</$checkbox>
</$set>
</$list>
