[Grammar] "help" in the passive

[angelene001]

I've read that:
"The verbs hear, see, make and help are followed by the to-infinitive in the passive"

I heard him cry.
He was heard to cry.

(but: I heard him crying ---> He was heard crying)

I've never seen an example with help in the passive.
Should it look like that:

I helped Tom (to) draw a cat.
Tom was helped to draw a cat.

Yes, but it would be an uncommon sentence, and obviously the 'I' has been left out, so it doesn't mean the same thing.
A teacher would not say, "You've been helped with this homework, haven't you?". They would say, "Someone helped you ..."
