Carlo Ancelotti refused to blame keeper Jordan Pickford despite his costly blunder in front of Gareth Southgate.
England boss Southgate was in the stands watching at Goodison Park as James Rodriguez’s fine goal saw Everton lead at the break.
Leicester fought back in the second half and levelled through Youri Tielemans’ low shot from the top of the box through a crowd of players.
Three Lions No.1 Pickford, 26, who has 30 caps, should have kept it out as the shot was close to his right hand side.
Pickford was also at fault for unnecessarily conceding a corner in the build up from which Tielemans scored.
Toffees boss Ancelotti assessed: “They put a lot of pressure on us but they didn’t have a clear opportunity.
“The goal was difficult because the view of Jordan was not so good.
“There were a lot of legs there and he had difficulties to catch that ball and unfortunately they scored.
“I spoke with the players but I didn’t speak with him directly about it and I am not going to – there is no reason.
“I think the result is fair and we have to be happy the team competed.
“We were able to score a fantastic goal through James and then we needed to defend.”
The draw saw Everton miss out on a chance to climb into the top four and keeps Leicester third.
Rodriguez’s goal, which he curled in off the post from the edge of the box with his right-foot, was his first since October 3 when he scored a brace against Brighto.
Brendan Rodgers’ Leicester are now unbeaten in nine games in all competitions.
Rodgers said: “They had that moment of quality with Rodriguez.
“But second half I thought the players were outstanding and we looked a really good side.
“If you can’t win, don’t lose and it was a good point in the end.
“We showed great spirit.”
