As shown in the image above from Jisho, 触る can be both transitive/intransitive for usage 1, but only intransitive for 2 and 3 This right now can't be reproduced on the site because of the way it display the entries, so 触る here is only marked as intransitive
this image above from Yomichan shows the tag "vt" for "verb transitive", and having similar compact tags that we could apply to different entries would allow to clearly differentiate between usage 1 and 2/3 in 触る
